Heads up Bold 9900 users - WIND Canada has just released OS 188.8.131.529. This is the latest official OS for the Bold 9900, so if you are looking for an update this is your answer. There are some higher leaked versions, but many like to stick to official OS versions on their device, so if you haven't updated your OS on your 9900 yet you may want to give this one a shot. If you do update, be sure to hit the forums and post your findings. As always, use caution when installing any software on your device.
