Right now, I have a Samsung Propel. TERRIBLE phone. It doesn't get reception anywhere! Anyways, my sister has the original iPhone and she's getting the new iPhone 3G S in September. She said I could have her old iPhone, to use until my upgrade date in January which is when I can buy a new iPhone 3G S. My only concern is, will AT&T consider the reactivation of the old iPhone as an upgrade for my number, thus pushing my upgrade date further away or will my upgrade date still stay at January 31, 2010? I'm just worried that when I plug the old iPhone into iTunes and reactivate the old iPhone, AT&T will consider that an upgrade for my number and push my upgrade date further away. Does that make sense?
