I can play mafia wars on my tour using the bolt browser. Certain flash functions are not accessible but the game is still playable. The other games like farmville that are fully flash will not work though.

I have wondered this as well..... I have friends with iphones and they can play the Zynga Texas Hold em and I really wish there was a way for me to do the same. The iphone does not support flash either, but the Zynga game works great and is really a beautiful app, I am starting to want an iphone....
Zynga now has MAfia Wars: Atlantic City for download i play on my torch, its great. It is connected to yer FB Mafia Wars in that you use the energy from FB to play the BB version.
