    When dealing in Soviet relations, President Reagan impressed upon a generation the mantra, "Trust, but verify." Decades later, this skeptical method is being applied to mobile carriers thanks to RootMetrics' Cell Phone Coverage Map, a crowd-sourced application aiming to provide reliable, verified information on network availability and performance. The app, now available to iPhone and Android users, provides a convenient way to determine which provider has the best signal in your area, and also happens to be great for spite, if you felt a coverage map wasn't telling the full truth. Yes, let's get it out of the way right now -- Root collects your stats and then sells it to the networks -- though given the purpose of the service, we're inclined to let criticism pass on this one. If you're undeterred by that caveat, hop on the bandwagon and share your results for the benefit of all (even if your battery doesn't thank you).

  • Skype calls not allowed over iPad 3G connections

    During our live iPad 3G first look this afternoon, TUAW readers were able to confirm that Skype calls still cannot be placed over the iPad 3G's cellular network connection. The Skype application will not connect those calls, telling users that, "You need WiFi to call over Skype." So what's the reason for this? "Skype calls over 3G networks are currently not allowed due to contractual restrictions." This should not come as a surprise. Skype has yet to release an iPad version of their software, and the iPhone-specific application has not received an update since early April. Testing the software on the iPad only confirmed that the same old things continue to work the same old way, regardless of the platform they were run upon. So why the big interest?

  • AT&T building out network capacity to prevent exodus to Verizon's iPhone?

    So this is what all those "yo' network's so slow" jokes were about. The Wall Street Journal has today penned a story framing AT&T's hefty recent investments in building out its network as a defensive move against a "huge exodus to Verizon" when its rival gets the iPhone. These preventative measures include working with Apple on streamlining the iPhone's network load, and infrastructure spending that is expected to be $2 billion more in 2010 than in 2009. The WSJ claimed yesterday that Apple was working on a CDMA version of its iPhone that could hit mass production as early as September. However, concluding that the iPhone on Verizon is a done deal seems something of a stretch. Sprint has shown a remarkable ability to attract cutting edge phones, and China Unicom's exclusivity agreement is about to hit its precarious first anniversary about the time this handset is set to roll out. Still, setting aside the analyst blather and extrapolation, the picture that emerges is of AT&T feverishly patching up its service offering in the face of a rapidly expiring exclusivity arrangement.

  • AT&T says Verizon's first LTE phone is 'going to be a fat brick'

    Ooh wee! Verizon and AT&T are getting all hot and bothered over the forthcoming LTE battle -- a battle which much like the current map wars, you can expect to grow weary of in about two minutes. According to a report in the Wall Street Journal today, both carriers have put reps in the limelight for a volley of tough talk. For starters, AT&T's CTO John Donovan claimed that Verizon was jumping the gun with its first-on-the-scene LTE rollout, suggesting initial devices are "going to drain the battery like crazy, and [they're] going to be a fat brick," noting that "2012 will be the time when you'll have decent handsets." Donovan lumped on the hits by also saying that "Anyone who says their network is ready for the iPhone -- or the broader mobile data explosion that AT&T has experienced -- is being naive." Of course, Big Red didn't just sit there and take it -- spokesman Jim Gerace fired back that "No matter how much our competitors talk, it's not going to slow us down," though he offered no further comment on the insults' stride-breaking potential. Both parties were mum on just how fleeced the consumer would be getting once the LTE pricing plans are announced, of course.
