All of a sudden my 3GS is barely vibrating :/

[ki2594]

So last night i was using my 3GS right before i slept and the battery was at 5%-ish and i noticed the vibrate all of a sudden got weaker. i guessed it was just for battery life so i put it on charge for the night as always. I woke up today, full charge, and still my iPhone's barely vibrating, its a VERY faint buzz that i can't feel when its in my pocket. I restarted the phone, still nothing. I'm currently restoring praying its just a software issue because i recently took off my jailbreak. Any ideas as to how to fix this? I've been looking around the internet for the past half hour for fixes but to no avail.

Thanks,

-Kay

This also happened to me. I ended up making an appt. at the Apple store. The "genius"(after first claiming it was caused by my case) took my phone in the back. He said he was going to take it apart and clean the inside. All I know is that when he came back, it worked as good as new. Then I bought the 3G S, and sold my 3G, so I'm really not sure if the problem came back or not.
