I bought the 4S on opening weekend but returned it within a few days because I felt it wasn't that much different than the 4. But yesterday I changed my mind and went out and got the 4S again. I turned it off a few times for something and each time I turned it back on, it was asking me for a facetime password, and iMessage password. I know the iMessage password is normal but I never seen a facetime password. Is this normal? Has anyone else got this?
