Seems it has been a while since a leaked for the BlackBerry Storm 9500. OS 188.8.131.52 has been leaked for the GSM BlackBerry Storm 9500. We don’t recommend you install this OS unless you have previous experience installing beta leaked operating systems. But if you feel like you really want to test out this OS then follow the link below. Please just be sure to do a full backup before installing it. Also word has arrived that RIM will no longer be working on any new OS 4.7 versions for the Storm. Seems RIM is starting to work on OS 5.0 now. With any luck at all we will see some leaked versions soon!
