Service wise, i've never had a problem. AT&T pretty much owns this city to the point where they have their name in the school stadium for christ' sake (Texas Tech stadium), so it's expected to have good service.
However, after having the phone for a few years, it's starting to get old in my eyes. Having the same thing for upwards of 2 years is starting to have its effect on me. Add that with the fact that now everyone and their moms has an iphone, and i just get kinda sick of seeing the thing around.
The Android phones are looking mighty good at the moment. Plus those commercials are really starting to appeal to me for some reason. Will probably sell my iphone and go the android phone/ipod touch route for a change, but holding on til i hear what Jobs has in store next til i make it official
