Hi guys, I have a question. My iphone 5's lock button is not working anymore and its a real pain in the ass, I have never dropped my phone, nor I mistreat the phone either. I have an appointment with the genius bar today but before I go I want to make sure I don't mess it up. I unlocked my phone through ebay, would it be an issue with the genius bar? Should i make a backup in case they give me a new iphone? Will i have to unlock it again if they give me a new one? Hope you guys can help me out. Thanks!
