Pearl 3G users haven't seen a new OS update in quite a while, but today we have one hot off the presses. SK Telecom has released OS 188.8.131.520 for the BlackBerry Pearl 3G 9100. Nothing in yet on whats changed in this one, but if you're using a 9100 or 9105 then fire up that USB cable and get to installing. Be sure to leave a comment with your findings. As always, use caution when installing any new software on your device.
