To be fair, if AT&T doesn't get their crap together, the iPhone may suffer. Unless Apple has a contract in which they are able to bail on AT&T, they are going to experience a drop in sales at least in the U.S. (I'm not sure if the iPhone is sold overseas, but I assume it is.)

AT&T is so bad that just recently (yesterday apparantly) they have stopped selling the iPhone in New York City, stating that "New York is not ready for the iPhone."

The truth though, as we all know, is that AT&T's network isn't ready for the bandwidth usage of it. AT&T was also recently rated the WORST cellphone carrier by Consumer Reports. No surprise, the number of dropped calls I got on AT&T was horrendous.
