Yep, there's a port of Sim City 3000 available on iOS and Android. It's not a bad port at all, to be honest.

The reviews of the iOS version are less than stellar.

I haven't had much problems with it, and have played it for quite awhile. It's crashed a couple of times, but never lost more than a couple of mins of gameplay. Definitely worth a couple of bucks.
