AT&T Mobility announced it was offering online account setup for Apple's iPhone 3G customers so they can take care of necessary requirements before they enter a store to buy and activate the phone.

The online account will allow users to have a pre-qualifying credit check done and determine eligibility on whether or not they can port a phone number over to AT&T's service. The move is intended to save customers time waiting in line at stores as the holiday shopping season approaches.

The account setup will also allow current AT&T customers to determine whether or not they can add a new line for the iPhone.
