Fix iPhone vibration problems

My iPhone 3GS vibration motor just went dead on me for no reason, luckily I have an app called iBrate, after double tapping on the screen which supposedly made the phone vibrate non stop, it's still not budging, in a fit of anger I hit it on my table and the thing went bzzzzzzzzzzzz. Caught me by surprise, after googling for similar cases, I found that using iBrate with slapping the phone's back on the palm is a solution for many. Guess it's time to get iPhone 5 as soon as it launches :)
