This is called Haptic Feedback, and it can be turned on/off here:
That being said, I cannot turn this off on my D2. I don't know if I have a bad unit or what, but maybe you'll have better luck than me.
Hope this helps...
I took my D2 into a VZW corporate owned store to report the issue (as well as the Wifi on/off cycling issue reported elsewhere), and they were puzzled why this didn't work. They looked at their internal KB and reported that no one else has complained about this issue so far. I asked them when they thought it might be resolved, and they basically shrugged their shoulders and said "we have no idea" and that it really wasn't that big a deal in the first place. Typical response, I guess. I suppose we'll have to wait for a future update to fix the problem...
I checked and this doesn't work on mine either. I also tried having it turned off and rebooting the phone. The option stayed turned off, but the phone still did the haptic feedback.
I have the same issue. It vibrates when my phone rings too. I have tried to turn oof the Haptic and all other vibrate functions are off. Who has the answer... Verizon stores seem to not have an answer. Tech Support??? Well when some one gets an answer or 2.2 includes a fix. I will continue to be annoyed at constant vibration. Oh...AND YES VERIZON STORE CLERK IT IS A BIG DEAL! To me the customer...maybe not to you...but it is to us in the forum with the issue.
