So I am out of space on my 16GB iPhone 4 and want the 32GB iPhone 4. I have this phone since the launch in June. My mom is eligible for an upgrade on her family plan (I am not on the family plan). Can she order the 32GB iPhone 4 online from Apple Store with her AT&T upgrade eligibility, give me the brand new sealed box, I can open it and switch my current microsim into the brand new 32GB phone, and sell my 16GB phone on eBay? Will there be any problems doing this (i.e. activation problems from the new 32GB phone)? Will it effect my mom's phone plan on her family plan account? Will there be any activation fees involved? How about upgrade fee by AT&T? When she orders the phone online should she put the current minutes plan I use for my phone, or her current phone plan under the family plan she is on? Thanks for any clarification.
