Sony Ericsson today announces the K618i, a slim and lightweight 3G phone that delivers an ideal 
mix of mobility, multimedia applications, and business solutions. Developed for those users that want entertainment on the move and a powerful business tool, the K618i 3G device is as light and slim as a typical 2.5G phone, yet delivers high-speed rates for streaming or downloading music and video clips, browsing the web, or gaming. And staying in control of email is made easier with support for push email, allowing messages to be sent directly to the phone without having to download them.
Well equipped for both capturing and sharing photos, and playing music, the K618i also features Bluetooth Streaming, to send full-length music tracks (or video clips) wirelessly from the phone and listened to on a compatible Stereo Bluetooth enabled device or headset.
