OK, so Street Fighter 4 went down to 59p on the UK iTunes stores the other day, an I was missing a decent fighter on my phone so thought fack it, why not gov!
Gotta say this version is very good, just as good as the originals if i'm honest! The gameplay is more or less the same, the graphics are nice (although the framerate does skip sometimes) and it's got all the best fighters there.
Download it an have a play, you won't regret it!
