T-mobile has released an official OS update for the BlackBerry 8900 and the 8520 OS version 220.127.116.112. It is nice to see carriers release updates and this one is not too far behind from what was leaked a while back. With the version this high makes me wonder how far RIM will keep updating this version of OS since these devices will not see OS 6 as far as we know.
You can download the OS by heading over to the T-mobile website at this link.
Remember: Although this is an official OS, if you run into any trouble please start by reading this 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. Don’t 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
