Hi Everyone, I purchased a regular (non-iPhone) plan through AT&T's web site yesterday. With the new 2 year contract, they are also sending me a free phone. I called AT&T and they told me that I need to send my free phone back or I'll end up with 2 contracts. This doesn't make sense to me. I know existing AT&T customers can just add the data plan and switch over to the iPhone. Does anyone have experience with this? I want to keep the free phone and sell it to offset the cost of the iPhone. Can I just use the free phone they sent me, and then after a few days, switch over to the iPhone, or do I really have to send that one back? Thanks for your help!
