There is a new leaked OS for the BlackBerry Storm 9530 floating around the web.  OS 5.0.0.973 is unofficially available for download, and seems to be quite a jump in version number from the last leak.  If you decided to give OS 5.0.0.973 for the BlackBerry Storm 9530 a go, remember, back up your device.  This is a leaked OS and is completely unsupported.
