Just like Beckeramos said, upgrading to the leaked .215 improves many things, including battery life. I would suggest you put down any liquid beverages, empty your bladder, loosen your belt a notch or two, close the door to your room so you don't disturb your family, close the window so you don't disturb the neighbors, take a deep breath, stick your tongue in your right or left cheek and skip on over to
http://www.droidforums.net/forum/droid-razr-support/217843-mattyps-215-leak-classroom.html, where you will both learn the proper methods of upgrading to .215, and while you're there you're also going to get a taste of some very funny exchanges.
Realize, the comedy is the SECONDARY purpose of the thread, although it may seem otherwise.
