At&t
As I told the folks at the Apple Store at The Woodlands, TX the iPhone is great, the biggest weakness is AT&T. Numbers through acquisition don't prove much except that someone is making money rather than providing good service. Where I live T-Mobile provides great service. AT&T does much less. If you want the phone you have to put up with the service or lack of whichever the case may be. Not everyone lives in the city.
