On my BB-S1, I could assign the length of the vibration to each message type SMS/MMS/Facebook/E-mail/Phone call. This was a valuable tool as I could tell what kind of action was taking place based on the vibration (i.e 10 short vibes was a phone call). Is it possible to do this with the DROID? All I can find is a vibration "checkbox" but not the length or the # of vibes. If anyone knows of an app that can do this, please advise - if there isn't one, how difficult is it for one of you developers do this?
