I may switch back to verizon from AT&T, I ordered the 16Gb in June 2010 for AT&T and have my own account and still have my account now with my iPhone 4. My question is, what exactly do I have to do in order to go from my AT&T account and go back to Verizon on my parents family plan. I know to cancel my account with AT&T(maybe pay a fee) but what should I do about pre-ordering and going onto verizon. thanks!
