I broke my iPhone 4s while I was travelling. So, I put it in my locker. I repaired it yesterday and connected it to iTunes. Unfortunately, My iPhone activated Activation Lock. Only one way to enter my Apple ID is to reset my password but, there is email that i don't know. It looks like g*****@m*****.com. g***** should be my email and I don't remember signing up with this kind of email.
What should I do?
