Hi guys, I am new at the forum, but long term Mac user and reader of macrumors. I look a bit arround your forum but did not find a solution to my problem so i will try to ask. My iPhone stopped vibrating. When i go into preferences and move the botton from off to on nothing happen. It was working up to a few days ago but now nothing. I tryied to reset the phone, change ringtones, downgraded and re upgrade, I am now on 1.1.2 on a jailbroken phone, everything work but i still don't get the vibration. Is there a solution to the problem? Is it the battery that vibrate? is it possible that there is an hardware problem? Please help me cause I really need that function to work.
