Sony Ericsson has unveiled three new handsets, marking the last major handset launches from the handset maker through early next year. The unveiling includes the K660 and two new Walkman phones: the W890 and the W380. The K660 is an HSDPA handset optimized for the mobile Internet with pan-and-zoom, home page, enter address and bookmark shortcut keys. The W890 is a slim candybar-style phone with a 3.2 megapixel camera, while the W380 is a Walkman handset with a clamshell form factor. The W380 has a gesture control feature that lets users mute calls at the wave of a hand.
