Another carrier getting in on the fun with this latest OS release that popped up in the forums yesterday. A1 (does anyone else want steak?) has just released OS 5.0.0.425 for the BlackBerry Storm 9500. We haven't seen an official OS for the 9500 since Vodafone dropped one a few months back, so you may want to give this on a shot. Direct download link is below so get to it. If you find anything new and exciting be sure to leave a comment and let us know.
