AT&T Service is Regrettably Awful....
Man.. this is bad news for me.. I would (along with my iPhone) switch back in a heartbeat. I live in central NJ, on the shore.. not exactly east bum-fart, and I cant use my iPhone in my house. It's a joke. I had Verizon for god knows how many years, living in NY and NJ and never had any reception issues... numerous "smart" phones.. Kyocera's (the big one and the 7135), Palm treos (600, 650 and 700). I'll tell you hand down Verizon's service (customer service and general issues of reception, etc etc); is completely in another league from AT&T.
I bought three iPhones on launch, June '07, and have consistently had the same feeling... if Apple really gave a rats A** about the end-user experience they would have NEVER gone with AT&T-Cingular. Apple's biggest concern was money first, their hardware second (all well and good, mind you); and finally I think they could care less what network it's on.
C'mon, in the US, who would in their right mind have taken Cingular's network over Verizon's (with money not being considered).
I'll be on the record as an early adopter to most new things Apple makes.. I bought 'em, I paid handsomely to break my Verizon contract... I would pay handsomely again right this second if they announced the iPhone for Verizon....
Ohh/.. and I wont be purchasing anything 3g from AT&T, because as you can imagine, even though I live in an incredibly populated area.... the 3G around where I live is barely existent.
