i went on homestarrunner.com and it work pretty well for me, and the process of installing was seriously cake, but there was no lag or choppyness at all for me, great thing added to my iphone today
The same thing happened to me. i went back and the Frash-0.02.deb file i downloaded first was empty so i try'd two other sites till i found one. Also you DO have to restart the phone after you are done.
I installed Frash using the three-step method, and it works pretty good. It displays flash ads, and I even got it to work on a 100% flash site for a nightclub.
However, it doesn't work very good with embedded youtube videos.
Better than nothing. Plus, the novelty value of flash on an iPhone is priceless.
