I was SSH'ing my iPhone (3GS) and I guess I got rid of something I needed because now it doesn't vibrate regardless of whether the sound is on. Is there anything I can do to fix/undo this? (There is also no sound when I send/receive text) Will upgrading to the new update, even though there's not a jailbreak get my vibrate back? Or am I screwed and I don't have it any more? HELP!
