RIM developing 5.0 OS for original BlackBerry Storm?This article contains unofficial information.
In case you were wondering, Viigo, Poynt and BOLT are some of the applications that work on the higher OS build. A list can be read at the source link. The new build was generally panned by the blog as not being productive and the feeling was that the last released OS (22.214.171.124 for the 9500) was faster and more reliable than the 5.0 build in the areas of the keyboard, browser, data and telephone. Of course, that doesn't mean that .92 will be the last OS starting with a 5. There probably is much more work that RIM will do on the software before it is ready for the public to use.
