Sound the sirens, as yet another leaked OS has surfaced. This time, it is BlackBerry OS 4.7.0.148 for the BlackBerry Storm 9530. As with any unofficial OS, it's possible that some features on your phone will not work, since this is beta software and not intended for commercial release. 

This is not an official release and is not supported by RIM or your wireless carrier.
