Got right through on that number. Interesting thing is the guy I talked to had to get permission to talk to me since that call center is in Arkansas and I'm in Little Rock.I just talked to some AT&T rep, she looked at my account and said I had no iPhone data package added (I am an existing customer). She said she added it and then transferred me to the "sync" department - where I am now on hold.
I would suggest calling to make sure you have the iPhone data plan added forsure, a lot of people selected it but it was never added it seems.
The # I called is 877-419-4500
I got two iPhones one for me and one for my wife. I started my activation Friday night and waited to do hers Sat morning. She had to move over from Alltel and I'm an existing ATT/Cingular phone user. You guessed it... Her phone is activated and mine is still in purgatory along with you guys.
I did find out there was a problem switching over from my blackberry to the iPhone. The nice tech corrected that and said I should be going soon... I'm not holding my breath.
