There is a new, very unofficial, BlackBerry Storm OS floating around the interwebs this morning.  You can find BlackBerry Storm OS 4.7.0.83 here.

CrackBerry.com has actually made a video of the new BlackBerry Storm OS in action and they say that it appears to be a “bit more snappy” than 4.7.0.75 which should have already upgraded to.  I am going to install it in a couple of hours and will post my thoughts here in the comments.
