By their very nature, you can’t count on plug-ins to work on every browser, but they are even less likely to be reliably available on the mobile web.
The Flash Player is a de facto standard in desktop browsers: Flash Player 8 penetration was at more than 99.5% as of September 2009. However, the mobile world is a very different jungle. Adobe is trying to bring the same experience to the mobile browser, but it has found many stones in the road. That is why Adobe as yet has no official up-to-date penetration percentages for the mobile world.
Adobe currently has two mobile lines: Flash Lite and the major Flash Player 10 for mobile devices. The first one is intended for low- and mid-end devices (and high-end devices shipped before 2010), and the major player will be available for Android, Symbian, and Palm Pre (but not iPhone) devices starting in 2010. Table 6-19 shows the ActionScript version and Flash Video support in the Flash versions available for mobile browsers.
