it is about time T-Mobile USA released an official OS update for the BlackBerry Bold 9900. T-Mobile is rolling out OS 188.8.131.522 for the BlackBerry Bold 9900, now this update is currently only pulling through Desktop Software at this time. I did check T-Mobile’s official update site and it is still showing OS 184.108.40.2064.
To pull the OS update simple plug your device in to your PC, open the BlackBerry Desktop Software and check for updates. Let us know if you see anything different in the comments.
Note: If T-Mobile USA is not your carrier please remember that you must delete the vendor.XML file prior to loading. The vendor.xml file located in crogram files>common files>research in motion>apploader to install it on a different carriers device. Also, we at Nerdberry.net do not accept any responsibility for any damages that are caused by loading this or any OS. If you are not comfortable loading an OS please do not proceed without first asking for help. Remember to create a BACKUP of your phone first via the BlackBerry Desktop Software
