On Tuesday, Adobe Systems released Flash Player 10.1 for mobile devices - but the rollout is going to take a while. The player is available first for devices running version 2.2 of Google's open-source Android operating system, but that upgrade is currently only available on Google's Nexus One smartphones being tested by reviewers. However, other Android-based devices are expected to get the upgraded OS soon. At some point, Flash Player 10.1 will also be available for mobile devices based on non-Apple platforms - BlackBerry, webOS, Windows Phone 7, LiMo, MeeGo and Symbian. Flash Player 10.1 offers user-interaction methods more aligned with mobile devices, including multi-touch, gestures, soft keyboards, and support for accelerator-based input, which enables Flash content to be shown in landscape or portrait mode. Smart Zooming allows content to be scaled to full screen mode from within a web page.
