If you have the Tour 9630, you may want to give this leaked OS a try: 18.104.22.1683, 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 22.214.171.1244 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.
