It is important that you take notice that this is not an official release, and is quite a bit harder to install. If at all concerened then dont do it be patient and wait for the official release.

RIM have removed the EXE file from the release, and you will also have to have OS 5.0.0.191 installed on your computer so be warned.

It has been a long time coming this release, but the boys at BBOS have just let the OS 5.0.0.230 for the BlackBerry Storm right out of the bag! Although the release has been hampered by the fact that RIM have managed to remove the EXE file but BBCrackman has found a way to create an installer without it! You can find full details of the link at BBOS please make sure you read the instructions carefully. Source – berryreview.com
