Iheard sometime in the past that a player (I can't remember who) managed to get Toribash working on his PSP. That was however an older version, but I don't see that the feat couldn't be done again, and if can work on a PSP then it might be able to work on an IPhone.
I think that ended up being a video. As in, the guy screen recorded Toribash, and converted the video for his PSP.
But I could be wrong.
