• Answer to: Why iPhone 4 doesn't vibrate?

    Hey, i have got easy steps to get it fixed. 1- Remove any protection (if u have used it) from your iphone. 2- download "ibrate" app from app store. 3- open ibrate app and after double tapping knock the iphone from back on the top left side (just like knocking on the door) 4- believe me it will start vibrating :) and allow ur phone to vibrate for At least two minutes as it will restart the jammed motors :)
