I was just wondering if I drop my phone or have any physical damage should I go to the Apple Store or to At&T since I bought the phone at the At&T store?

I've brought my phone to the Apple store twice in the last year. Once because I dropped my iphone and again because I thought my iphone was dead. (Turned out it wasn't dead, I just needed to do a hard reset. The dropped phone was a whole different issue!)

The folks at the Genius Bar are great — really helpful. However, I suggest making an appointment with a genius. You can do so online at Apple's website. It's free, too.

AT&T is probably not going to give you a replacement phone just because they have more to sell. I heard they're even trying to get rid of the free bandwidth policy and start limiting access.

They're getting cheaper faster than they're getting more generous!

Sorry, can't help you about the White Screen of Death. That the heck is that??  Good luck with that anyway… But in response to the topic, I know you have to send your phone in. They won't take it back at the Apple store. It's called beurocracy
