ok so my iPod is on a 3.0 jailbreak and it worked fine for a long time, until my friend locked me out of it for an hour. Now it seems to freeze all the time, and the only way to turn it on is to hold both the power and the home button. Sometimes it freezes on the apple logo sometimes when im listening to music. I can can still hear the music but my ipod is frozen. Then i have to hold down power and home to turn it off. Also sometimes when i do get it on there is no sound with or without earphones. I have tried restoring it and jailbreaking it again but this has not fixed the problem. Is there anything i can do?
