How much is an iPhone from AT&T & how much is the monthly bill?

Ok. Not much info from you but I'll try. Ok. The 4s in 16gb is 200$ with a contract. It increases by 50 $ everytime you add 16gigs. The 4 is 100for 8 gigs. The 3gs is 1 $ for 8 gigs. All of these phones prices are with a contract.

The monthly bill can be anywhere from $45-65 depending on what's included in the plan.
