About 6 months ago, I went to fix an old iPhone 5 to a computer repair shop, it took a couple of weeks for me to get my phone back because they never called and I always forgot to call them to see what was going on. It sounds so irresponsible but I didn't actually need the phone, I just wanted to get it fixed so I could give it to a family member that needed it but we had no hurry so I always forgot. ANYWAYS, after some weeks, I went back to the shop and found out they had moved to a new location and with the hectic move they forgot to call. They gave me "my phone" without a charge and told me they couldn't fix it. I went home a little disappointed. I've had this phone for months just laying around the house and never threw it away. Today, out of curiosity I turned it on and the "connect to itunes" message popped up. I got so excited. It gave me the option to update or restore so I chose to update it. Then it asked me for my passcode, I enter it and it tells me it incorrect. I reconnected to itunes and a message pops up telling me if I want this computer to access the information on "KTs iPhone?" but my name is not KT. I instantly realize the guy gave me the wrong phone. I restore it and use my current phones sim card bc it had none but it won't let me sign in with my apple ID. It wants KTs apple ID. Is there anyway I can use my apple ID instead of KTs?
