Experiences with the iPhone and AT&T

Maybe I'm beating a dead horse here, but I've been using the iPhone for 6 months now and here are my reactions so far:

• I like (not love) the interface. It's pretty intuitive overall, but being someone who prides myself on usability and interface design, I cannot for the life of me figure out how to customize the programs list. This is something that's so simple to do on many other devices, but has been puzzling me for months. Even for the customizations that are there, they're very limited on what you can do. C'mon Apple, you can do better.
• Holy dropped calls!!! I used to have Verizon, and Sprint before that. In the past three weeks with my iPhone, I've easily have had more dropped calls than my entire prior experience with Sprint and Verizon combined (20 vs 1 or 2). I had one 40-minute conversation that was dropped three times in the process. And it's not like I'm in a dead zone either ...
• AT&T customer support. There seems to be a LOT of talk about their support, and even though the support staff seems friendly, they don't seem too terribly good at getting things done or answering my questions. For example, I signed up with a coupon code to receive a discount on every bill. Since July, I have not received one statement that honored that coupon code. Each bill, it seems, I have to contact support to get this fixed, and them I'm assured it won't happen again ... until my next bill comes around ...
• iPhone apps. Love em. Enough said.

I'm left wondering if my phone's issues are related to AT&T or the iPhone? AT&T, when contacted about all the dropped calls told me it was a bug in the iPhone. I'm not so sure about that though ... So, with that said, I'm stuck here with 1.5 years left on my 2 year contract. If I leave early, I'm sure there's a hefty fee (although, according to this article, it sounds like a breach of contract on their end to me). If I stay, I know I'm going to continue getting crappy phone service. To be honest, going back to Verizon with the Droid is looking very inviting to me right now ...
