Got a call to my cell phone from 781-936-4241 at 2:40 PM on Apr 09, 2009.  I let it go to voice mail since I did not recognize the number. Surprised to find a voice mail message on "to reactivate warranty coverage this is the final call before we activate the file". Press...".  At which point, I quickly delte it!  BEWARE!
