Can I keep my iphone of I switch to AT&T?

I have an iphone with sprint and my contract ends in July but I want to switch to AT&T because it's going to be a lot cheaper the sprint the only reason I went with them was because they had unlimited data but I realized I don't need it! Is there any way I can keep my iphone when I make the switch because I really do not want to pay for a new phone!

No. Your phone is locked to sprint for CDMA and they won't give you an unlock code either even if you pay an early termination fee. Best thing to do is just pay the etf and just trade in your phone for another one. I think best buy has the 5s for 1 dollar if you trade in an iphone.
