Ok everyone, I have successfully upgraded to the leaked OS126.96.36.1992 for my BlackBerry Bold 9900, and so far with everything installed, and updated, like BBM back to version 188.8.131.52, and other pre-installed IM clients, such as WLM/Yahoo/GMail, plus other applications that may not be updated to the latest version, so please check via BlackBerry App World when you have the chance.
I noticed, with the tip from ToraxCefiro it was brought to my attention via the Networks and Connections, scroll down you will now see a brand new feature, called Media Server, which is above NFC, and below BlackBerry Bridge. (pictures below)
Overall, the OS has been one of the best (leaked) OS I've ever installed, and for me to say something like that, is very rare.
So if you own a BlackBerry Bold 9900, please don't hesitate, and go for the kill, this leaked OS will not disappoint.
