Answer to: Why iPhone 4 doesn't vibrate?I am back on this forum to say that I did download the IBrate app and it did solve my problem like I had mentioned on my previous post. However, I noticed that after a few days, it stopped working. I deleted and downloaded the app again--but it didn't work this time around. I can't understand why it worked only for a few days and now its not. Go figure!! It must be the internal mechanism that is misaligned.
