Flash on browser?

Now that Apple is allowing third party browsers on the App Store, could someone release one with flash support, or would that have to be a system update from Apple? Sorry, I don't understand this very well.

 

They just aren't allowing it at all yet.

 

As far as I am aware these 'browsers' are basically safari with another skin and some other variables passed to it to improve it. I believe they all use the same core code and same rendering engine, so I doubt that you can put flash in it as it stands.

 

those are not 3rd party browser, it's safari underneath it all.
