If you're a straight shooter and only indulge in official releases who happens to be a TELUS customer, you can no go ahead and fire up BlackBerry Desktop manager and get updated to the official OS 18.104.22.1687 for either the BlackBerry Bold 9900 or BlackBerry Torch 9810. You can also go ahead and check for system OS updates on device as well if that's how you want to roll, though folks have been having more luck with desktop manager.
The downloads aren't yet available on the TELUS BlackBerry downloads page but that's only a matter of time. If you're already running the leaked version, then no matter -- stay on that release as it's identical anyway. If you need help along the way, you can head into our help forums or check out some of our BlackBerry 101 articles including How to Install or Upgrade to a new OS. If you do install this OS, hit up the forums thread below for findings, fixes and more discussion.
