First at all, Hi guys. I thought I should post my problem on that forum since you looked quite nice and you maybe could help me... (By the way, I'm french, so, sorry for my bad english) Ok here is the thing : My iPhone (3G, 2.2 firmware, jailbroken) doesn't vibrate anymore in the games or app that can have this feature (like the cydia "massage" application) BUT still vibrates when in silent mode, or in the parameters menu. So it's clearly not a mechanical problem. Anyone here got this problem before? Any advice? Thanks in advance.
