iLounge has posted a set of two new high-definition hands-on videos of Apple’s iPhone 4 today, one focused on the externals of the new phone by comparison with the original iPhone and iPhone 3GS, and the other on its new software and interface.

The first video is a comparison of the iPhone 4, original iPhone, and iPhone 3GS (YouTube HD link), showing the final, working phone from all angles. It’s also available from Vimeo.
The second video is a full interface video for the iPhone 4 (YouTube HD link), showing off everything from FaceTime to iBooks, iMovie, iOS4 multitasking with the new Pandora application, and the iPhone 4’s other built-in applications. It’s also available from Vimeo.

Both videos are in 720p format.
