BBleaks has posted a link for OS 22.214.171.1243 for the the BlackBerry 8530. This OS is not an official OS & you should install only if you know what you are doing. This new version is quite a jump from the first one we saw which was .463 . Share in the comments any problems you find or areas where it has been improved.
