How much is an iPhone 5 with an upgrade from an iPhone 4 from AT&T?
If you are eligible for a contract upgrade or are new to ATT, its $99 and up. (Depending on the size of your memory) Otherwise it's the full price of the phone.
I THINK ITS LIKE $250 BUT IT ALL DEPENEDS ON THE GIGABYTES
Just phone alone is $199 with upgrade. Amount of gigs will be in your data plan. That will be separate and will be on your monthly bill.
