So I know AT&T is charity to traffic for latest iPhone 3GS buyers to barter their indication for the latest iPhone 4;I’m clear for this given I purchased cave on Jun 2nd.
Â
What I was wondering was how you would go about you do this. Do we:
Â
A) Pre-order the phone on Jun 15th and have it sent to a internal AT&T store. We afterwards go in with the 3GS and perform the sell right there and then.
Â
B) Return the 3GS ASAP, afterwards pre-order the phone on the 15th and afterwards come in to collect it up at no additional charge? (Assuming there is no cost disproportion in between the sell models)
Â
Any help?
