As well as promo videos of the Xperia X10, Sony Ericsson released four videos of its staff giving us a run through of the Android handset. This includes Erica Kato Marcus, Head of Application Planning, about the new signature apps: Sony Ericsson Timescape and Sony Ericsson Mediascape.

The UX interface certainly looks amazing, it’ll be interesting to see how smooth it will run come launch day. For those interested in the white paper, you can download it here. Check out all four videos after the break.
