My iPhone stopped to vibrate yesterday. I restored it to 1.1.1, jailbroken it, and did anysim. Unfortunately it didn't help. But after an hour or something the vibrations started working again, it was working in the evening, but today in the morning it's off again. In setting i have vibrations on, tried to turn it off and on again, but this won't help. Does anyone have a solution for that? What should i do with the phone? oh, besiedes, i don't have the recepit so i can't use the warranty.
