Another official OS popped up a few days back that we seemed to miss. Vodafone Egypt released OS 18.104.22.1680 for the Storm2 9520. No word on whats new and improved, so if you give this release a go be sure to drop a comment and let us know. If you're using a 9520 on another carrier, just delete the vendor.xml file before you try installing. As always, use caution when installing even though this is an official OS.
