Verizon, T-Mobile take top honors in latest J.D. Power survey
We typically expect to see T-Mobile top J.D. Power's wireless customer satisfaction surveys, but it seems Verizon's been sneaking up on the peeps in pink. In Volume 2 of its 2007 study -- Volume 1 having come out in May -- Verizon has ended T-Mobile's 5-period streak atop the rankings, scoring 726 on a 1000 point scale to take the crown. To be fair, T-Mobile slides in just one measly point behind at 725, but it's still gotta smart a bit to lose the title. AT&T, Alltel, and Sprint Nextel round out the top five, scoring 708, 695, and 679, respectively. Not even Verizon really deserves to pop the bubbly here, though, seeing how the survey represents a 12-point slide in industry average satisfaction year over year and a 7-point decline since the last reporting period. Maybe the whole prorated ETF fad will start to turn things around?[Via MobileBurn]
QRIO befriended by toddlers in study
Remember that study which placed a bubbly QRIO in the middle of rambunctious 18- to 24-month old kids in order to better analyze human-robot interactions? We know, it's probably coming back ever so slowly, but regardless, the findings of the five month trial have finally been published, and the results are less than shocking. Essentially, researchers noticed that children learned to treat the QRIO as if it were another human; the Earthlings eventually felt comfortable touching its hands, covering it with a blanket when it laid down and helping it back up if it toppled over. Notably, kiddos even went so far as to shun the poor bot when it was programmed to dance nonstop, but they forgave the bizarre antics and continued to play nice once the jig was up. The crew involved with the research is now focusing on the development of autonomous bots for the toddler classroom, and while much more testing will likely be done before any conclusions are definitively drawn, results from this go 'round sure hinted at just how susceptible we are to robotic takeover, er, playing nice with harmless androids. Oh, and be sure and check the video after the break![Via Slashdot]
Rogers Wireless brings 7.2 Mbps HSPA trials to Canada
Today is shaping up to be Rogers Wireless day in these parts, as the announcement of a 7.2 Mbps HSPA trial has fired up in Montreal and Brampton -- Brampton? We've seen 7.2 networks lighting up here and there and are pretty stoked to see this in this neck of the woods -- and certainly hope to see this catch on quickly. While no details are mentioned in the press materials -- like, can this be accessed by the public or is it closed -- we're gonna do some digging and -- if possible -- armed with a data card, some testing.
iPhone report: most owners left Treos, Sidekicks behind
While we've seen a variety of surveys pitting the iPhone against its most notable rivals, a recent study conducted by the NPD Group breaks down the numbers behind who left what phone (and what carrier) to acquire an iPhone. Not surprisingly, iPhone early adopters were "ten times more likely than other new phone buyers to have previously owned a Treo and three times more likely to have owned a T-Mobile branded phone, such as the popular Sidekick model." When it came to carriers, Alltel and T-Mobile were said to have lost the most customers to AT&T, as consumers who "switched carriers to buy an iPhone were three times more likely to switch from Alltel or T-Mobile than from other carriers." Notably, the lack of "corporate email support" was pinpointed as the main reason that many BlackBerry users didn't make the leap, but it did praise the iPhone for helping to "bridge the gap between consumer-focused feature phones and productivity-focused smartphones."
Greenpeace dismantles iPhone, discovers "hazardous chemicals"
Apple's no stranger to being slammed by Greenpeace, and while Steve certainly spoke of a "Greener Apple," it seems that the iPhone wasn't included. According to tests arranged by the entity, it was found that the iPhone contained "toxic brominated compounds (indicating the presence of brominated flame retardants) and hazardous PVC," which are said to be disallowed across the pond due to RoHS requirements. More specifically, the independent testing found "brominated compounds in half the samples, including in the phone's antenna, in which they made up 10-percent of the total weight of the flexible circuit board." As expected, Greenpeace wasted no time pointing to rival firms that have received pats on the back for their green efforts, and subsequently shook a finger at Apple while murmuring "tsk tsk" -- but we'll leave the actual politicking to you all in comments, cool?Update: Greenpeace does not claim that Apple is in violation of RoHS.[Via Switched, thanks Laura]
Study investigates relationship between walking and talking
In of the less glamorous studies we've seen, a team of researchers from a variety of universities came together to study the possible link between walking and communicating via cellphone. In essence, researchers reckoned that by rigging up a Windows Mobile-based handset to vibrate slightly to the rhythm of one's footsteps, the other participate would simply fall in line (and have a more enriched experience) without actually being near the other individual. In testing, however, it was noticed that although the vibrations did help synchronize participants' steps when they were reciting scripted dialogue, a fair amount of subjects managed to mimic each other's gait sans assistance when carrying on a genuine conversation.

Cellphones are dangerous/not dangerous, hearing loss edition
Apparently, talking on a cellphone for 60 minutes or more per day can result in a partial loss of hearing -- at least that's what some researchers in India are saying. The scientists conducted an experiment to test the correlation of hearing loss to the average use of a cellphone call. The experiment covered 100 participants with cellphone usage ranging from four years and over to just started using a cellphone. The results? Long-time users seemed to suffer some high-frequency hearing loss, usually in their right ears -- the ear most commonly used for chatting on the celly. There also seemed to be some correlation between warm, full, or ringing sensations in the ear, so if you're experiencing any of those, enjoy the stealth ringtone while you still can.[Via textually.org]
iPhone trumps HTC Touch, N95 in usability study
We've given you your chance to choose a champion amongst the iPhone, HTC Touch and LG Prada, and while the latter wasn't included at LG's request, the other two were recently pit against Nokia's N95 in a study of usability. The test was reportedly conducted by Perceptive Sciences, a Texas-based usability consulting firm, and relied on data from just ten individuals who had "never used any of the three devices." The group was asked to "perform a series of tasks on each handset with quantifiable results, such as the time needed to find and use the on / off switch," and when all was said and done, the iPhone managed to snag the gold. Of course, we wouldn't take these results to be the bonafide truth, but if you're interested in seeing what all the mobiles (and guinea pigs) went through before a winner was chosen, head on over to the read link.[Via iLounge]
Cellphones are dangerous/not dangerous, just a hint edition
Researchers across the pond at the UK Mobile Telecommunications and Health Research Programme (MTHRP) are without a conclusive answer on the short term effects on the brain from mobile phones. After a six year study on the effects of mobile phones on brain and cell functions, researchers found what's to be described as a hint of a cancer risk when exposed. Does anyone else feel a little nervous with non-scientific words being used to describe negative consequences of something most of us do on a daily basis? Leave a comment if you can break the medical jargon![Via textually.org]
iPhone price drop leads to sales boost
Shocking, we know. As if the price drops on the PlayStation 3 weren't evidence enough that we all like our gizmos a bit cheaper, a new report from Piper Jaffray analyst Gene Munster claims that iPhone sales skyrocketed shortly after the (hotly contested) price drops. According to his math, Apple needed to sell some 136,000 iPhones between September 5th (the day of the cuts) and September 9th (the day Apple claimed to have sold one million of its mobiles), which meant that 27,000 iPhones per day were getting unboxed in the five-day period. Comparatively, Munster approximated that Cupertino was unloading around 9,000 iPhones per day prior to the price cuts. 'Course, even Gene doubts that the recent sales surge will be able to hold steady, but we'd say the slashings have already had their desired effect.[Via DailyTech]
Cellphones are dangerous/not dangerous, low brain activity edition
Dutch scientists seem to be binging on cellphone studies lately, with their latest research pointing out that frequent mobile phones users have lower brain activity. In the study conducted by Radboud University of Nijmegen and Brainclinics Diagnostic, groups of 100 frequent, infrequent, and non-cell users were compared. Apparently the frequent user's brain activity was the lowest in the groups studied -- though top points were scored on focusing on specific issues -- but still fell with "normal" ranges. So in the future, if you see the number of typos here start to climb rapidly interspersed with fits of drooling, apparently that's the sacrifice we're here to make.
Cellphones are dangerous/not dangerous, hospital edition redux
Well, in true dangerous / not dangerous fashion, the bit we did on cells being safe to use in hospitals has been rolled over and proven false by yet another study. The BBC is reporting that in a study performed by Dutch researchers, the case for mobile phones interfering with hospital equipment has been stregthened. The group tested 61 devices, and the majority could be affected by mobiles -- though no word on what was considered as "affected". Of all of the equipment poked at, six intensive care ventilator systems behavior was classified as hazardous as they are plugged directly into patients. As a side note, 3G handsets are less likely to cause problems, but don't appear to be completely guilt free.
Planet Earth: now home to four billion phone lines
Go on, pick your jaw up off the floor -- this isn't that staggering, now is it? Considering all those cellphones that have been sold here recently, and the plethora of folks who just refuse to ditch that landline, four billion total phone lines seems just about right, truth be told. According to the International Telecommunications Union, our planet is now home to about "1.27 billion fixed lines and 2.68 billion mobile accounts," but the total number of people represented by these data is much less clear. Notably, the study found that "61-percent of the world's mobile subscribers are in developing countries," and further added that China and India were greatly to thank for reaching the milestone. And just think, there were less than 1 billion lines combined across the globe just 11 years ago.[Image courtesy of OwlRecruitment]
Cellphones are dangerous/not dangerous, cell division edition
So apparently, virtually all existing official limits for radiation emitted by mobiles (FCC, we're looking at you) are based on the assumption that the dangerous effects of that radiation are caused by heating of the brain. Pretty big assumption, eh? A new study by Israel's Weizmann Institute of Science suggest that some "non-thermal" forces are at play, though, noting that chemicals involved in brain cell division were affected in tests on rats after just 10 minutes of exposure to cellphone radiation. Improper cell division goes hand in hand with cancer, so the finding is a rather alarming one. Of course, you know the drill: for every study that suggests phones are dangerous, we can certainly dredge up one that says they aren't -- just be forewarned that a cool brain isn't necessarily a healthy one.[Via CNET]
Study suggests 100% mobile phone penetration in the US by 2013
We know, that "100-percent" figure may be a bit tough to wrap your mind around, but let's give it a try, shall we? Current estimates reportedly suggest that "nearly 84-percent of the US population will have mobile phones by the end of 2007," and according to SNL Kagen, that figure should shoot to 100-percent in just six years. Notably, 100-percent penetration does not mean that every single American will own a phone, as it's estimated that some 18 to 20-percent of us will be using multiple mobiles. Additionally, it was noted that data usage / revenue could become increasingly important as newcomers to the wireless world grow fewer, but that tidbit certainly isn't taking anyone by surprise, now is it?[Via mocoNews, image courtesy of JevaTech]
Study finds no link between car accidents and yapping whilst driving
If you're ready for a healthy dose of unconventional wisdom, you've come to the right place, as a couple of confident graduate student economists at UC-Berkeley are purporting that there is "no match in the evening cellphone use spike and crash data." Basically, the duo is suggesting that although we've been on the mobile horn a lot more these days, the number of fatal vehicular accidents over the past 18 years have not experienced the same leap. Weird logic, we know, so take it for whatever it is (or isn't) worth.[Via Wired]
Poll: Americans overwhelmingly against texting while driving, in theory
Be honest, when's the last time you responded to a text message from behind the wheel? If you're in with the majority of cellphone-toting Americans, you've done it -- though you probably also think it should be outlawed. A recent poll of about 2,000 US adults found that some 57 percent had participated in a little SMS action while driving at some point in their lives, but they were at least cognizant of its danger, with 91 percent guessing it was as dangerous as driving on a couple drinks. We'd guess as much, too -- if not more so, considering that texting takes brain function and your eyes away from the road. 89 percent of the polled folks want the practice outlawed, which really makes us wonder about those two percent that know it's dangerous and want to keep on doing it. Let us know to stay away with a bumper sticker on your jalopy, k?
It has a name, part II: "smexting"
It turns out that cleaner air and healthier people aren't the only side effects of a "No Smoking" sign. A wide-reaching ban on smoking in enclosed places just went into effect on July 1st in the UK, and in the two weeks following, carrier Orange reported that 7.5 million more messages were sent on its network than in the two-week period the month prior. Analysts (who apparently are responsible for researching these sorts of trends) suggest a couple explanations: first, smokers freshly ousted outdoors to get their smoke on need something to do to pass the time -- out comes the phone, and, well, you know the rest. Secondly, smokers that are working on quitting as a result of the ban are turning to texting to give their fidgety, nerve-wracked fingers something to do and to seek support from friends. The behavior, which arguably didn't need a name, is being called "smexting." Looks like the money saved on cancer sticks is going straight to the carriers -- but hey, at least it's a little safer (or not).[Via Techdirt]
iPhone survives freezing temperatures, won't work with gloves
It's been a tick since anyone was brave enough to put their mobile through frozen conditions after that whole i-mate JAQ ordeal, but a fellow at f-secure did manage to put his own iPhone to the test to see just how well it would operate after a half hour in the freezer. Though Apple lists the "nonoperating temperature" as -4° to 113° Fahrenheit, this particular iPhone chilled out in -4° temperatures for 30 solid minutes before finally escaping, and while the touchscreen wouldn't respond at all to glove-covered fingertips, bare hands managed to show that all functionality was still in tact. Granted, it wasn't frozen in a block of ice or anything, but folks residing in bitterly cold locales can rest assured that their iPhone will indeed survive the frigid winters to come. Check out the video after the jump.[Via TUAW]
Luxembourg leads cellular market penetration
Color us surprised, it seems the market leader for cellular penetration -- at least in the 30 "Organisation for Economic Co-operation and Development," or OECD countries -- is Luxembourg. With some 153.7 subscribers per 100 people -- apparently attributed to multiple SIM cards per person -- they are knocking the socks of us over here where penetration is about 70 out of every 100. Other interesting tidbits include Japan and Korea where 3G subscriptions surpass 2G and Canada which is next to last in penetration rates to Mexico. The compiled data covers the years between 1980 and 2005, so if you love this type of info -- we all know, nothing beats dropping these type of tidbits at a social gathering -- hit the read link to grab yourself a free copy.[Via InformationWeek]
