We're seeing a trend of official 5.0 firmware popping up on carriers in the last few weeks and I'm loving it. One thing BlackBerry users crave is a solid carrier-released OS to play around with. Vodafone UK is the latest to offer up a release with OS 22.214.171.1246 for the BlackBerry Storm2. This is a decent step up from their last offering, so give it a go and let us know what you find out. Although it's an official OS, always use caution when upgrading.
