Hello everyone! So i have an iphone 4s unlocked to Tmobile by the GPP sim on IOS 7. So i know on IOS 6 before that if you wanted to use the unlock on another iphone you had to buy a new activation code. But now since you unlock via jailbreak do i need to get another activation code? Because my phones power button is broken and i would like to just go into apple and get it replaced because my warranty is still in effect and all that fun stuff and i just would like to know if i need to buy another activation code or not because i would rather not if i don't have to. thank you.
