The BlackBerry Storm2 was originally said to eventually get OS6. However, due to the touchscreen sucking up too much memory, OS6 did not perform very well. Therefore, it was decided by RIM to not pursue releasing OS6 on the Storm2. Nevertheless, we now have a strange build of OS 5.0.0.1015 that has dropped. We're not sure how much higher the next build will go or if we may see builds of 5.0.1.x in the future.
