WEIRD PROBLEM-- PPC 6700 will not vibrate??

[sprint_user101]

I obviously installed or did something that is not allowing the phone to vibrate anymore. I know it's not a hardware issue because the same thing happened yesterday and I took the phone to a Sprint store to exchange for a new one. Now it's happening again. When I got the new phone yesterday, I made sure that the vibrate mode worked. Then after I installed the new AKU 3.3, the vibrate mode was still working. It was something that I did to either the registry or by installing a program and/or hack.

I had Phone Alarm on there, but un-installed it. I also un-installed Microsoft Voice Command. Still won't vibrate!

This is driving me nuts!! Any idea what might be the culprate?
