Sonic the Hedgehog 4 is actually looking just as sweet on the iPhone as it does on the bigger consoles - and it'll be portable which is a bonus.
This new trailer from Sega shows how the various worlds in the game are coming along in the iPhone and iPod Touch version of the game, which looks to be pretty much identical to the other versions.
Although we're not too keen on the way that the world spins when Sonic goes around a loop, rather than Sonic himself. Still it's a must-have game on the Apple machines though, surely. It's out later this month.
