So I'm having issues with an intermittent\sticky home button on my iPhone 5s, so I'm thinking of taking it in and having it replaced under warranty. When I bought my phone, I bought it using an ATT upgrade, and then i had it unlocked a week later. When I check the provisioning profile, it shows SIM unlocked, and I know I have unlocked because my T-Mo sim works in it too. My question is if I take it in and they replace the phone, will the unlock status carry over to the replacement? I'd assume it would have to since the phone I'm taking in is unlocked, and I'd expect the same in exchange, right? My friend seems to think if mine was unlocked, and it's replaced under warranty, the replacement will be unlocked as well. Anyone know for sure one way or another?
