Same boat as 90% of you on this board. No prob at Apple Store, but activation wouldn't go through. Called probably four times between Apple and AT&T over last 14 hours...nothing. I called one last time today, got the most helpful person in the world at AT&T. She figured out that the problem was my verizon account information *had a dash* in the middle of the number, and it cannot accept dashes (why iTunes didn't tell me this i don't know). Anyway, she fixed it, activated my iphone right over the phone while i was talking to her, and now i can make outgoing calls AND receive incoming calls. My iPhone went to brick to FULLY working (ported from Verizon) in 40 minutes with my phone call. I also got an email from AT&T saying congratulations that my number was ported. Call up AT&T and ask if all the info you entered into iTunes looks correct...they'll probably find something that's clogging it all up.
