A guy has created a new hack for jailbroken iPads that ports Flash from Android to the iPad. The port works well and allows Flash games and content to run on the iPad using a compatibility layer.
The designer says that a release will be made once Frash is stable. Right now, it only supports the Jailbroken iPad, but the developer hopes to add support for the iPhone and iOS4 later.
Frash is a port of the Adobe Flash runtime for Android to the iPhone, using a compatibility layer, by comex (twitter). 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.
Frash uses a multi-process model similar to Chrome on the desktop, so a crash in the Frash/Flash plugin doesn't take down the browser. You can see this while I'm playing Alien Hominid: the ad above crashed (probably a Frash bug), but Safari stays open just fine, and continues to play other Flash content on the page.
Video and keyboard input are currently not supported. The former will require major reverse engineering of the video decoding frameworks on the iPhone, but the latter should be reasonably easy to implement.
