Well I'm on T-Mobile Germany, so whatever.
By the way AT&T is a very good network for Apple to go with as it was the
only one interested in the iPhone in 2007! I guess the guys at Verizon were too busy admiring themselves to see the potential in the device. Now they realized they fucked up and started this silly iDon't ad campain as a pathetic try to conceal their incompetence. As far as I know they also didn't accept Apple's App Store idea. I don't think Apple will switch to Verizon anytime soon.
Doesn't T-Mobile sell the iPhone too in the USA? I would think that they should have a pretty reliable network over there. Or was that in Canada? In Germany they are great: almost 100% coverage, great EDGE and UMTS coverage and speeds.
