For those of you who want to get pre-approved for the iPhone (or you're worried about your credit), take the following steps:
1. Call AT&T at 1-888-333-6651.
2. Choose option 3 for new service, and then 3 again.
3. Tell them you're interested in buying the iPhone and want to get pre-approved. They'll ask for your SSN, ID, address, etc. They'll run a credit check and let you know if you're approved or not.
4. Be sure to ask for a BAN number before you hang up. This BAN number is good for 30 days.
5. After buying your iPhone on Friday, enter the BAN number in the "pre-approved credit check code" field during activation.

Just one less thing to worry about.
