Hacker intercepts phone calls with homebuilt $1,500 IMSI catcher, claims GSM is beyond repair
In 2009, Chris Paget showed the world the vulnerabilities of RFID by downloading the contents of US passports from the safety of his automobile. This year, he's doing the same for mobile phones. Demonstrating at DefCon 2010, the white hat hacker fooled 17 nearby GSM phones into believing his $1,500 kit (including a laptop and two RF antennas) was a legitimate cell phone base station, and proceeded to intercept and record audience calls. "As far as your cell phones are concerned, I'm now indistinguishable from AT&T," he told the crowd. The purpose of the demonstration was highlight a major flaw in the 2G GSM system, which directs phones to connect to the tower with the strongest signal regardless of origin -- in this case, Paget's phony tower. The hacker did caveat that his system could only intercept outbound calls, and that caller ID could tip off the owner of a handset to what's what, but he says professional IMSI catchers used by law enforcement don't suffer from such flaws and amateur parity would only be a matter of time. "GSM is broken," Paget said, "The primary solution is to turn it off altogether." That's a tall order for a world still very dependent on the technology for mobile connectivity, but we suppose AT&T and T-Mobile could show the way. Then again, we imagine much of that same world is still using WEP and WPA1 to "secure" their WiFi.
iPad 101: Conserving your 3G data use
Since I brought home my 3G + Wi-Fi iPad a little over a week ago, I've been running in Airplane Mode with Wi-Fi enabled to avoid using cellular data. Otherwise I kept getting a prompt (shown here) asking me if I wanted to setup an account, which I didn't want to do. Fortunately, there is another way. Go into the Settings application and tap on "Cellular Data." This brings up an on/off switch for Cellular Data and Data Roaming. Turn both "off" and you will not be prompted to sign up for a data plan when Wi-Fi is unavailable. Airplane mode disables not only the cellular data, but also Wi-Fi, Bluetooth, and the GPS. If you are only trying to avoid using cellular data, there's no need to use Airplane Mode. If you have upgraded your iPhone to iOS 4 then you also have the ability to disable cellular data under Settings » General » Network » Cellular Data, which may come in handy if you have a metered account with AT&T.
3G technology: Yesterday, today, and tomorrow
Cellular technology has been evolving since its invention. With the first cellular telephone networks, developed by Bell Labs and AT&T, cellular technology began to make leaps forward in ease of use, voice quality, and data communication. The miracle of technology we know today as the cellular phone was made possible by a steady stream of innovation that continues on into the future. The history of cellular technology starts at Bell Labs in the 1960's and 70's where they began to iron out the details on what a commercial cellular network would be. A cellular network is a network of base stations, or antennas, that form large pockets (cells) of radio signal coverage that overlap. With a technology called "handover," if you made a call using one base station, and you then moved out of that base station's range and into another base station's area, your call could be "handed over" to the base station that was closer to your location. These base stations allowed you to make calls to other cellular phones or to wired landline phones. Over the years, the evolution of cell phone technology has been broken up into "generations." It started with the first generation (1G), and it continues to the upcoming fourth generation (4G). In the beginning, cell phones weren't much more than huge walkie-talkies. Over time, though, they evolved into the data powerhouses that we carry around in our pockets.
Best iPhone cellular plan... ever?
I like to joke that "Iowa is a great place to live, but I wouldn't want to visit." Residents often complain that there's nothing to do (other than milk cows and shuck corn). One can only stand so much antiquing. But we do have a few things going for us: clean air, relatively light traffic, lots of space, and perhaps the best cell phone plan for the iPhone. Recently, reader PC Drew, a US Marine living in Japan, sent us a note to let us know about the challenge he had in finding an iPhone plan while visiting his wife's family. A contract plan was out of the question, of course, because of his length of stay and the fact that he's still under a two-year Softbank agreement in Japan. And due to AT&T's, shall we say, "perplexing" lack of a prepaid plan for the iPhone, the official carrier in the States wouldn't help him. He could have stopped by a Best Buy and picked up an O2 Universal SIM Card for less than $10. That would have provided the ironically-named PC with $0.17 per minute calls but that's it -- no data, no included text messages, and no tethering ability. After searching a bit for a prepaid solution, he stumbled across the MEGAtalk Nationwide plan from regional GSM carrier, i wireless. This no-contract, no-credit-check offering gives the customer 30 days of unlimited calling, with roaming and long distance, for $49 plus taxes. But wait, there's more! Not only did PC get unlimited voice minutes, but he also had unlimited SMS texting and, here's the kicker, unlimited data usage. And, with the proper hack, i wireless customers can tether their iPhones for free. Yes, you read that right... free tethering on an unlimited data plan! Of course, getting a service plan from an unofficial carrier (read: non-AT&T, at least in the United States) requires your iPhone to be SIM-unlocked. This has become much easier over the past two years and most cell phone shops can perform the procedure if you're too nervous. PC had already performed the necessary steps, as he often finds himself in areas that aren't exactly covered by his Softbank contract. Okay, now for the downer. Because it's a T-Mobile affiliate, i wireless doesn't offer iPhone-compatible 3G service. In fact, they only offer EDGE speeds in their Iowa-based footprint, unless you're traveling to an area with T-Mobile 3G. As a result, that unlimited data is a bit crippled speed-wise, but it's still a heck of a deal. So, if you're planning on traveling to Iowa -- say, to Fort Madison for the 62nd Annual Tri-State Rodeo in September -- or if you're "lucky" enough to be stuck living here, you might want to take advantage of what's probably the most economical cell phone service plan available for the iPhone anywhere in the USA.UPDATE: Quite a few readers asked if this plan is available outside of Iowa, so I contacted i wireless directly to find out more about its policy. Yes, you can sign up for this plan, even if you don't live in the i wireless footprint area, however, the representative I spoke with pointed out that this plan may expire at any time, which would seriously affect the customer's ability to use his or her phone effectively. If you are interested in further details, please contact i wireless directly. DISCLAIMER: I own a computer and cell phone store that sells this particular prepaid plan. But the above story is absolutely true; PC Drew did contact TUAW to brag about his bargain find, without knowing me or my connection to the product.
Forum post of the day: Mobile love
Recently, rumors have been spreading about a mobile application for WoW. Blizzard has been trying to get some information through a series of mobile service polls on the forums. Bornakk began a poll regarding the number of times forum users have downloaded games or applications for cellular devices. In the cellular era, Blizzard appears to be making our favorite MMORPG more mobile friendly. Many of the posters indicated that they have the latest in smartphones and thus are constantly adding new aps. This will likely encourage Blizzard to provide better mobile support. This will be handy considering that they have been resistant to third party mobile applications.
New agreement integrates satellite / cellular technology in mobile chip
SkyTerra's Mobile Satellite Ventures, ICO Global Communications and Qualcomm have jointly announced today a partnership that could have far-reaching implications in the mobile realm. In short, the trio has agreed to "integrate satellite and cellular communication technology in select multi-mode mobile baseband chips," which will essentially enable handsets to have "ubiquitous mobile communications coverage from anywhere in North America, including areas where traditional cellular service is currently unavailable or unreliable." The release proclaims that this hookup will lead to satellite connectivity being in mass-market devices, but only time will tell how long it takes for compatible handsets to get adopted by carriers. Unfortunately, we do know it won't happen prior to 2010, as that's the planned ship date for the newfangled chips. Thanks for the heads-up, guys -- but oh, how the tease hurts us.[Via PhoneScoop]Update: Images provided are of Mobile Satellite Ventures' design concepts. %Gallery-32429%
TUAW Tip: Using your iPhone on a cruise ship
If you're going on a cruise vacation, don't be concerned about being out of touch. Chances are excellent that you can use your cell phone.Reader Steven Madow reminded TUAW that many cruise lines use a service called Cellular At Sea to provide you with satellite-linked cellular service. Almost 100 ships currently use the service, which is a joint venture between AT&T Mobility and SeaMobile.Madow said that with his iPhone, configuration was a simple matter of looking at the settings (right) for a carrier called "Cellular at Sea." The cost of the service varies depending on your home carrier, but for AT&T users it is about $0.79 per minute. While that's not exactly cheap, it's priceless if you need to keep in touch in case of an emergency.Most cruise lines also provide Wi-Fi based onboard Internet service. Rates for these services usually range from $0.75 per minute down to $0.30 per minute. The more time you prepay, the lower the rate is.To find out if your favorite cruise ship has Cellular At Sea or Internet service, click the Read link or visit the website for the cruise line.Thanks for the tip, Steven!
iPhone vs. the world
BusinessWeek.com has a really interesting article online today theorizing about the potential impact the iPhone 3G will have on other smartphone manufacturers and the wireless industry at large. The $200 introductory price point can lure lots of customers over to AT&T and put the price crunch on other smartphone manufacturers. Plus, now that the phone has been out for a year, consumers are more eager to upgrade. As the article points out, the trend of cell phone carriers subsidizing the price of handsets was on the wane, but now that the iPhone 3G is going to be released at a subsidized price, other manufacturers might want to follow suit, and that may mean cutting their prices on bulk orders. Even before the 3G announcement last week, Apple has already forced the other mobile players to up their game. Not only are future phones adopting more iPhone-centric interfaces and features, wireless carriers who can't offer the iPhone to their customers are spending more to remind users of their offerings. According to the BusinessWeek article, Verizon's ad budget increased 30% in the first quarter of 2008. While AT&T is surely going to continue to benefit from being the sole iPhone carrier in the United States, they also stand-out as being expensive. To help cover iPhone subsidies, AT&T is raising the data plan $10 a month. As BusinessWeek mentions, this could be an area that other carriers could seize on. By offering more features for less money, other carriers have an incentive that while not as flashy as the iPhone, might be more financially practical for lots of customers. Still, as I said in last night's talkcast, I think the $200 price point is going to vastly reduce the barrier to entry for lots and lots of users. The data plan price increase is going to be more a determent for existing iPhone users, not new users to the fold. Just as the iPod really hit its stride when it became available for under $400, the $200 pricepoint on the iPhone is going to be extremely tempting for anyone approaching the end of a cellular contract. The other phone manufacturers SHOULD be concerned; the war for mobile domination will not be won or lost based on the iPhone 3G, but Apple is a very, very deft opponent.
Analog cellular networks, R.I.P.: 1983 - 2008
Marking the end of a remarkable era in cellular technology, the FCC is officially letting American carriers decommission their legacy analog networks as of today, February 18, 2008. Few of us still own a phone based on AMPS -- Advanced Mobile Phone System, ironically, despite the fact that there's been nothing "advanced" about it for many years -- but we owe the very existence of the world's modern wireless infrastructure to the introduction and overwhelming success of the Bell Labs-developed technology. So successful was AMPS, in fact, that it eventually covered virtually 100 percent of the continental United States, a statistic CDMA and GSM have only recently begun to approach.
Nokia announces user-generated mini-games for new N-Gage
Personalization is all the rage in games these days, what with Miis, face-mapping and, er, laser-etched portables showing up all over the place. Now Nokia's jumping into the personalized gaming, uh, game with the Yamake initiative for the new N-Gage platform.According to the announcement, Yamake mini-games (because "ya make" 'em ... get it?) will lets users add "personal content such as text, pictures, sound clips and movies from the mobile device or PC" to create picture puzzles, trivia quizzes and more. Sure, it doesn't sound like anything you can't already do online, but the ability to create and share these little personalized games easily on your phone might be cool. Trust us ... even if you don't get it, your little sister will love it.[Via Engadget]
Modu mystery unravelled, look ma, a modular handset
Mystery solved, modu is of course, a modular cellular handset -- the answer was in the name the whole time, clever. The fun begins with the idea that the actual handset can be slipped into "modu jackets" which let users completely change the look of their handset without having to replace it -- we see the potential for way too much glittery gem-encrusted foolishness here. The other half of the deal is slapping the modu into different modu-enabled consumer electronics, or "modu mates" -- think car stereos, photo frames, DAPs, and whatever else you can dream up. If we were betting types, we think modu is on to something pretty interesting here, and it seems with likes of Blaupunkt, Universal Music, and SanDisk already onboard, the Q4 launch might prove to be something special. We don't have any pics showing detail or any technical specs handy just now, but rest assured, we're going to be all over them at Mobile World Congress for more info.
The 4G war: has WiMAX won, or will Verizon choose LTE?
In a wrap-up of the state of 4G networks over at BusinessWeek, the battle between the three competing 4G network standards -- WIMAX, Long Term Evolution (LTE), and Ultra Mobile Broadband (UMB) -- is appraised, with WIMAX clearly edging out its other rivals. This could be a two horse race before long if Verizon chooses to back GSM's successor LTE over CDMA's sequel, UMB. That would leave Qualcomm without one of its most significant backers for CDMA's spiritual sibling, although it'll do just fine thanks to the multiple 4G patents it holds. Ultimately though, in all of this space there's very little discussion about what the consumer wants: do we really need two or three different standards that probably won't inter-operate, leaving us back at the square we've always been at? Frankly, for all the benefits that 4G is purported to bring, we'd like something a little more imaginative than the usual bickering amongst the big shots.Update: Although it didn't come from VZW, last month Vodafone's chairman Arun Sarin made it clear that Verizon will go for LTE. Bad news for UMB!
OQO confirms Model 02 delays, EV-DO modem to blame
While OQO has certainly had its share of ups and downs over the past few years -- from us calling the Model 01 the "heavyweight champion of vaporware," to literally having a market segment spring up around the devices -- things looked to be headed decidedly up with the release of the 3G-capable Model 02 at the start of the year. But as always with the San Francisco company, the transition between announcing a product and actually shipping it is proving to be a little difficult. With shipping delays stretching to 16 weeks, an OQO rep recently confirmed the problem and pointed the finger of blame: "All orders with Sprint and Verizon customers are on hold while some issues are ironed out with the WWAN product line." Engadget pal Boy Genius says his experience bears that out -- his commercially-purchased Model 02 has no software support for the supposedly-present Sprint modem, and to make it worse, the unit he received is covered in nicks and scratches, more evidence of hiccups along the OQO production line. Although we enjoy talking to the guys over at OQO, it sounds like they really need to get their ducks in a row with the Model 02. Peep the full Boy Genius rant with photos of his nicked-up Model 02 at the read link.
Let your fingers do the objecting
Excuse us if this post has a typo in it or something. We're dividing our time between writing it and packing up all our worldly possessions.You see, it's ... well, there's a Gyakuten Saiban 4 cell phone theme for the FOMA 903i that makes your phone's menu look like the game's menu, and puts GS4 backgrounds, animations, and sounds on the phone. It even has special screens associated with things like sending mail and receiving phone calls.Every time we use our only partially-themed phone (which only has a Phoenix Wright background and ringtone, and nothing else) causes us pain. We have to go to Japan, immediately.
AnyTrack GPS-100 discretely tracks personal property
Considering that behind-the-back GPS tracking isn't exactly illegal now, AnyDATA is offering up the option to discretely track just about anything (or anyone) you please with its AnyTrack GPS-100. Similar to other GPS / cellular hybrid devices we've seen, this rendition utilizes the AnyTrack "wireless location service" in order to continually track your mischievous teen's car or suspicious spouse. The diminutive 2.65-ounce unit can purportedly be tossed in a glove compartment, planted on a jacket, or clipped onto your dog's collar, and by taking advantage of the built-in GPS antenna and CDMA connectivity, the GPS-100 doesn't even need to be outdoors in order to transmit data. The gizmo itself will run you $199 for a limited time, while a potentially pricey pay-pay-view rate schedule will run you anywhere from $14.95 to near infinity depending on how obsessed you are with watching the dot.
BMW shows off WiFi / cellular-based in-car multimedia system
Among all the new cars unveiled at the recent Geneva motor show, BMW also took the opportunity to show off a little in-car action, letting show-goers take its still-in-development dashboard console for a spin. According to Wired blog Autopia, the system can be loaded up with audio and video content off your PC via WiFi while you're parked in the driveway, or via a cellular link when you're on the road. Unfortunately, they didn't provide many details on the console itself, other than that it boasts 20GB of storage and will apparently be able to record radio content as well. It's also not clear when we might see such a system installed in a future BMW, with the company only saying that it "could" be commercially available within three years, adding that licensing and copyright issues are (not surprisingly) the main things holding it back.[Thanks, Christian]
Actiontec unveils range-extending Wireless FMC Router for mobile / WiFi hybrid phones
For those of you who happen to be in the predicament of owning a svelte hybrid cellular / WiFi phone, yet can't get cellphone service back in the boondocks where you reside, Actiontec is kicking out a range-extending router to help you make and receive calls on your mobile handset via WiFi. Touted as a "world's first," the Wireless FMC Router acts a standard four-port 802.11b/g/n router, supports WPA2 / WEP, and comes with a rather robust firewall to keep your conversations guarded from snoopers. Additionally, it facilitates call switching between the mobile and home WiFi networks as users move in and out of the house, giving you the option to connect via your cellular network or over VoIP with the same handset and same number. Aside from acting as a "middleman between the broadband and cellular networks," it can connect / drop from the WiFi / mobile networks on-the-fly while conversing, and can purportedly support "all major carriers" as well. So if you're thinking of consolidating the amount of phone numbers attached to your name, and don't mind picking up a hybrid handset, this multifaceted router will be able to simplify your conversations for $179.99 when it lands in Q2.
Next OQO handheld PC could have cellular capability
Jon Fortt over at The Utility Belt has been informed by "someone who would know" that the next iteration of the OQO will feature cellular capabilities, along with other improved specifications including a brighter screen, a better keyboard, more RAM, and a larger hard drive, all at the same price as the current model -- um, can anyone say Osborne Effect? With the addition of some form of wide area wireless network access, the OQO would become even more of a "middle" (subnotebook / ultra-UMPC / über-smartphone) device than it already is, and since we're in an indulgent mood, we could even envisage a time when cellphone carriers give the OQO the most glorious feature of all: subsidies. That prospect, dear ladies and gentlemen, gives you one more reason to mark your calendar for the start of the Consumer Electronics Show on January 8, as Mr. Fortt was told this was when the new OQO is to be unveiled.[Via Handtops]

Rumor: Playstation-based cell phone?
Evidence is mounting that Sony is at least looking into the possibility of adding cell phone functionality to the PlayStation Portable, or adding PlayStation-branded content to other cell phones.The first clue came last week when Sony Computer Entertainment corporate executive Izumi Kawanishi admitted in an interview with Japan's Nikkei BP (translated by IGN) that using the PSP as a cell phone was "a possibility" that he is personally interested in. Of course this idle chatter is far from anything official, but the idea seems like a natural progression for a system that will soon be able to do everything from playing movies to taking photos.Then, early this week, CNet Asia noticed that Sony Ericsson Senior VP Rikko Sakaguchi mentioned at a conference that the company "is working on something" with regards to a PlayStation phone, but that "the surprise must be kept for the future." Again, nothing even close to official, but considering that classic Playstation games will soon be downloadable to the PSP, could cell phone emulation be in the cards as well?(Pictured: an existing skin for the i330 cell phone, not meant to represent any sort of actual Playstation phone)Read -- Kawanishi interview on IGNRead -- CNet Asia Blog post
