Hey guys so I still have an AT&T Iphone 3GS and have been waiting for the new Iphone "5" or whatever it is before I make the switch. My question is, I have an update obviously and was curious...should I buy the Iphone "5" form AT&T and than leave my contract? Or how does it work? Won't I get charged a fee of leaving anyway before an upgrade or using the upgrade? Is it cheaper since I am eligible or an upgrade? Also how do I exactly make the switch on release day? My whole family has a plan on Verizon and I will just be joining. Sorry for the confusing. Thank you!
