I recently had my iPhone 3g stolen, and purchased a new one the following day after canceling the stolen phones IMEI, etc. The new phone was defective, so I had to return it the next day. After spending over 3 hours in the AT&T store they were unable to activate my data plan because switching iPhone to iPhone apparently there is a period of limbo transferring in the AT&T system. Now I have no data, thus email, and because voicemail on the iPhone is intertwined with the data plan, no voicemail. I can't even change my voicemail greeting to tell people that I cannot check voicemail for up to 2 weeks until they get this problem resolved. Has anyone had this issue? How long did it actually take? I love the iPhone and have had no problems up until this switch and its driving me to the point of giving up. 2 weeks without mobile email for my work could be catastrophic.
