Flash on iPhone?

Anybody know how to get it? I am aware that there is a way to get it but i have lost the thread that told me how to do it! (If i remember it was on another forum)
 
I thought that was one of the downsides of the iPhone/ipad, that they didn't support flash?

If this is do-able, I am very interested!
 
You only can do it if you jailbreak your iPhone.

As far as I'm aware, there isn't any other "legal" way of doing it.
