Back in early July, we talked about a new way to get Flash compatibility onto your iPad that involved a program called Frash. If you want flash on your iPhone 4 you can do that now to with Frash support for the iPhone 4.
The software is in an alpha version, which means it will not be perfect and may cause you some issues on your device. The person who ported Frash for the iPhone 4 is Comex, the same geek that authored the Sprint and JailbreakMe tools.
If you are excited to get Frash onto you, iPhone 4 you can check out the video below for the directions to make it happen. The version used will also work on the iPad and iPhone 3GS.
