We're going to have to wait until June to see proper native iPhone games, when Apple launches the official App Store for its handset.
However, that isn't stopping developers from launching some cool web-based games for iPhone, which you play through its Safari browser. The latest is a 3D version of the Rubik's Cube.
Developed by a chap in Baltimore called Balazs Peter Vagvolgyi, it's presumably unofficial, but is pretty neat all the same. The cube sits onscreen surrounded by a bunch of arrows, which you press to rotate it.
Fancy a go? You need to point your iPhone browser to http://www.vagvolgyi.com/rubikscube/rubikscube.html and then tap away to your heart's content.
