Solution for no vibration on iPhone 3GS

Argh, seems like iPhone 3GS has issues with is vibrator. For some mysterious reason, my iPhone stopped vibrating, Although some people blamed the missing vibration problem on firmware issues, however already I had the most recent firmware on.

Then I stumbled upon this tip which pretty much says to turn on vibrate and hit the phone from the back with your palm. It actually started to vibrate after a couple of tabs to my surprise 88|.

Anyway, if you find that the vibrate keeps going off again, simply download one of those free vibration apps. For me I used iBrate, and kept running it (hitting it when it stops) until the vibration became constant. I did a few cycles of that (ie starting and stopping the vibration) and it was fine after that!
