Another day, another update. The Storm 9500 is the latest device to be graced with new software as Vodafone Australia has officially released OS 188.8.131.521. We saw another official 9500 release a few weeks back, but this one looks like a pretty decent jump from there. If you do install it, drop a comment and let us know your findings. As always, even though this is an official release, use caution when upgrading the OS on your device.
