Jerry let me know that he spotted OS 22.214.171.124 for the Storm on CrackBerry Forums. This leak seems to original from another site but the boys in the forums put up their own mirror download sites. One of them kindly ripped out the RIM Tools that is included in the download. If you still find it installed then make sure to uninstall it before upgrading your OS.

Let us know what you find in the comments and kudos to BloodBath18 for compiling the download links.
NOTE: Do not install this software if you do not know what you are doing. It may make your BlackBerry FUBAR or just plain angry.
