YouTube is reporting an astonishing fact - since the iPhone 3GS launched on Friday 19 June, uploads from mobile phones have increased by 400%.

This statistic is likely a blip, as those with the new handset are keen try out its video capture and upload to web functionality, but it appears to show the impact such a launch can have.

In fact, uploads from mobile phones to YouTube are growing steadily as manufacturers, such as Sony Ericsson, offer simplified uploading features.

YouTube reveals that in the last 6 months, uploads from mobile phones to video sharing sites have jumped 1700%.
