China Unicom has made a bunch of BlackBerry Bold 9900 owners happy today with the launch of a new OS for the device. This brings OS 18.104.22.1687 officially to the Bold 9900. Hopefully this fixes some of the calling issues I have been having with .402.
Warning: This OS will NOT install on any other BlackBerry besides the one mentioned above. If you do not know how to upgrade your BlackBerry OS 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.
