I just jailbroke my iPod touch 4G using green poison. It seems fine, but when I first jailbroke, it asked for my FaceTime password, when FaceTime is not even set up on my iPod yet. Like literally, i unlocked my iPod after the jailbreak and the keyboard pops up with a little box for my password. It seemed very weird. Then, when I open Processes in SBsettings, I see FaceTime there, and I did not even open Facetime. When i close Facetime, the iPod resprings. Is this normal?
