Frash is an effort to try and get Android's Flash implementation on iDevices. It is going to be on jailbroken iPad's and is developed by comex, the one behind the Spirit Jailbreak. It is only on the iPad at the moment, but they are trying to get it on the iPhone as well.
Frash is a port of the Adobe Flash runtime for Android to the iPhone, using a compatibility layer, by comex ( http://twitter.com/comex ). Frash can currently run most Flash programs natively in the MobileSafari browser. Frash currently only runs on the iPad, but support for other devices (3GS+ only due to technical restrictions) is planned, as well as support for iOS 4.
A release is planned for when Frash is stable. Developers are welcome to join the effort at http://github.com/comex/frash – fork it and send a pull request with your patches.
