OS 4.7.0.122 for the BlackBerry Storm 9530 has been available to Bell users as a update to BlackBerry Desktop Manager since last week, however, the latest Storm 9530 OS is now up on the web, essentially making it available to whomever wants to download it.
You can get OS 4.7.0.122 from Bell at the link below. Just remember that if you are not a Bell BlackBerry Storm user (read Verizon or Telus users), your carrier will not support you if you run into any issues.

Note: Installing 4.7.0.122 on something other than a Bell BlackBerry Storm is a little different than installing any of the many leaked OSs that have come before it. Since .122 is carrier specific, you need to delete the vender.xml file from C:Program FilesCommon FilesResearch In MotionAppLoader after installing .122 to your desktop. Once you’ve done this just run loader.exe from the same directory. There is no need to install via Desktop Manager.
