If only they could get it working on an iPhone then some enterprising hacker could start harvesting iris scans using the recently publicised exploits and hey-presto! We can all start getting into Steve Jobs's biometrically guarded throne room using a picture of his iris held up to the camera.

The image makes it look like you can do it with the front (videocall) camera. But this is usually a much lower res device than 1megapixel - it's the rear camera that usually has the MPs.

There are a few mobiles out there with swivel cameras, but otherwise, trying to take a picture of your iris without being able to see what you're doing is liable to take a tad longer than 0.5 seconds...
