Anyway, have you tried holding the sleep/wake button and home button at the same time for ten seconds?
 
Ouch, sorry to hear that. You may just need to wait it out, and if it continues for too long take it to an Apple store. Never heard of this happening before
 
Mine actually did this randomly on the other day. The phone was on standby (not plugged in) and started to vibrate as if there were an incoming call but screen would not light up. A hard reset stopped it. It's been a few days and all has been fine...
 
I've tried everything. It may sound funny but the screen is black, won't stop vibrating, and the computer doesn't recognize it.

When you say force restart, do you mean just turning it on and off or holding the sleep/home button down for 10 secs?

If that's not working I'd get it to an Apple store if possible, or call a priest.

Keep us posted.
 
Have you tried unplugging it and letting the battery die? Then recharge it and see what happens?
 
I just charged it to 100%! I texted my friend, unplugged it, put it on bed, then noticed it vibrating... constantly. I've held the sleep and home buttons down for 30 seconds and nothing happens. My computer doesn't recognize it either =(.
 
Plug it into your computer with iTunes running and hold the buttons for a while. It might be in DFU mode.
 
I just unplugged my iPhone 4 from charger and the screen went black and it will not stop vibrating! I plugged it back into the wall charger and tried my MBP but it won't stop. I tried force shutting it off but it won't recognize any commands.

I've had the phone since launch day and haven't had a problem until now. Can someone please help!

i say immediately bring it back to apple and askin tell them u wanted the actually phone, not a the sex toy version
 
Still won't recognize it after two more attempts. I've held the buttons down since I read your post. It's been vibrating for 50 minutes :|.
 
I had this happen on my 3GS its caused when the casing in the upper left corner by the mute switch breaks causing it to trigger the vibration even though the switch isn't actually being toggled.

Same thing happened to me the day I got my phone. I tried every hard reset possible and nothing worked. I finally had to just let it die. Took about 5 hours of constant vibration. When I woke up the next morning it was fine. I took a video of it when it was vibrating and showed it to the guy at the Genius Bar the next day and after some hassle he gave me a new phone. Make sure you take a video to show them the problem or else they won't believe you!
 
put it in a good use if you have a gf :D

anyways... try plug it in to pc/mac and hold down the power/home button at the same time of a few seconds..
 
I've tried the force restart countless times. It has now been over an hour and it is still vibrating. I took a 1:50 video showing that it won't restart, won't show up on iTunes, and the actual vibration. I am leaving for class and will post when I get home if it is still vibrating and I will upload the video.

hahaha make sure you wipe your pants when you get home..
sorry couldnt help it
 
Happened to my first on. It freaked when a call came in (which i couldn't answer because the screen went black). Holding home and sleep for a while eventually made it stop and reboot.
 
This is new functionality actually, when iPhone gets to cold it's starts shaking from the cold, just try to put it somewhere warmer.

Good Luck
