PPCGeeks - Phantom Vibrations ????

I have had my Sprint Diamond for a few months and just the other day it started to vibrate on its own. At rest or while using it, a pattern of 3 quick vibrations occurs. The duration of the Vibration is that of a soft reset and the spacing of the 3 vibrations is milliseconds. The pattern repeats itself sporadically. I got a set of these vibrations 10 minutes apart recently and usually they are hours apart. The Diamond can be in a rest state such as when I am sleeping and it just goes off with the pattern of 3 vibrations. My Diamond is always set to vibrate. The recent program changes before this started to occur were:S2U2 upgrade from 1.50 to 1.52 I removed 1.50 & 1.52 and it still occurred although I may not have removed all of the files. WMWirouter upgrade from 1.25 to 1.30 These are the only changes I made to the Diamond prior to having the phantom vibration issues. It may just be a coincidence that the vibrations occurred shortly after the above changes.I also downloaded a Debug version of Magicall a couple of days ago to help the software developer work out a bug I am having which is not a vibration issue. The Vibration issue just started last night though shortly after the S2U2 and wifrouter changes. iI am trying to be as thorough as I can explaining the history of this vibration issue. I appreciate any feedback regarding this issue.
