I have a plan so I can get the iphone 4 soon. My carrier is sprint. My contract doesn't end until septempber 2012 but my dad contract ended so he can get a new phone. So.... He can get the Iphone 4 which is in a really good price right now. And after a day of getting it, deactivate the iphone and active a old phone to his number so then I will active the iphone to my number. Do you think this will work!????? Thank you and please answer ASAP
