Well I want to say this is a leaked OS 18.104.22.168 but its a little more complicated to install then a regular OS leak. The team at OSBB scored OS 22.214.171.124 for the BlackBerry Torch 9810 which brings the Wi-Fi hotspot functionality many people were asking for. The unofficial installer they bundled it in requires you to install OS 126.96.36.1990 for the registry keys before installing this OS. You should then be able to load it with the work that OSBB has put into the installer to strip out many Thailand specific files.
You can check out the details over @OSBB if you are adventurous.
