The BlackBerry Storm was one of the earliest BlackBerry models to have an upgrade option to operating system 5.0 available for it. Tracking real world operating system use through downloads of Pixelated (the second most popular game in AppWorld) has shown the gradual decline of the older OS4.7 as the newer OS5.0 has become more popular.
Adoption of OS 5.0 on the BlackBerry Storm 9530 in August climbed up to 89.9% of all users. This is up 3% from July and is the largest month-to-month increase since May. At this point there is little reason for developers to worry about pre-OS5 touch screen devices, as there are hardly any left (although this is not yet true for non-touch screen devices such as the 8520 and 8900).
