for the last 2 months my iphone hasnt been vibrating on its own, the only way i can get it to vibrate is if i give it a firm smack below the headphone jack.

i just took the phone apart, ran the ibrate program for a constant vibrate, and started to fiddle with the vibration peice. it looks like it only will vibrate when i hit the motor or spin it a bit with my finger.

i'm assuming that the motor is probably fried or on its last leg, so i was going to order a new backplate with all the new peices mounted.
