It may be experimental and reference an animal you've never seen, but Adobe has released Wallaby to help developers convert Flash content into HTML5. In theory this allows the Flash content to be viewed on iOS devices including the iPhone and iPad. Apple has been clear about it's dislike for Flash technology, and will not allow plug-ins to view Flash content on its devices.
Steve Jobs claimed the technology was outdated and inefficient, and Apple has much to gain from its own App Store content. Adobe has been battling the Flash restrictions from the beginning. The company has been working on Flash app development tools, which were stalled temporarily when Apple changed the terms of its developer agreement to ban the tools.
