I got an iPhone 5 couple months back on eBay but before I bought it, it was on AT&T. The guy who I got it from said he would unlock it if I bought it (Which I did). Ever since then my phone has been working fine... Until now. My home button is not working and I'm planning to take it to the apple store today. But before I take it I wanna know if apple will give me a new unlocked iPhone or will I be getting an AT&T iPhone 5 and have to unlock it myself?
