The iOS version of the game features improved graphics and draw distance, plus three different control schemes including support for made-for-iOS controllers on iOS 7. You can even create your own custom playlist on your iDevice and load it into GTA: San Andreas's "Mixtape" radio station.
Rockstar is currently working on versions for Windows Phone (coming next week), Android and Kindle Fire. The iOS app, which runs on iPad 2, iPhone 4S and above, is priced at $7.
