If you have the Tour 9630, you may want to give this leaked OS a try: 22.214.171.1243, as indicated by BlackBerry Leaks. The leaked file is HERE, hosted at Multiupload.com so I suggest you waste no time because these links have a tendency to be taken down shortly.
Just out of curiosity, note that BB Leaks also has a leaked version of OS 126.96.36.1994 for the upcoming Pearl 9100 and 9105. Two models that haven’t even hit the stores yet. Wow, that is impressive.
Alright, if you do not know how to upgrade your BlackBerry OS please start by reading this great step by step guide. Don’t forget to delete the vendor.xml file located in c:program files>common files>research in motion>apploader to install it on a different carriers device.
And never forget our usual warnings: do not download and install these updates if you don’t know what you’re doing. Incorrect procedure or just bad luck could render your BlackBerry inoperative or unstable.
