A sleek clamshell camera-phone, the Sony Ericsson Z520i is designed for style-conscious users who want to carry an attractive accessory just as much as a mobile communications device. Available in grey and white models, the quad-band GSM handset features an ingenious light effect, which uses blue lights built into its perimeter. The setup lets a user know who is calling by flashing one of eight light patterns, which are paired with melodies and linked to phonebook contacts. The Z520i measures 83x46x24mm and weighs 94 grams, fitting snugly in the hand as easily as it does in a pocket or bag. Its camera can take pictures or video clips with the handset open or closed. The camera lens is on the same side as the external screen, which acts as a reference viewfinder. The main 1.8-inch display shows full-resolution pictures when the phone is open. The Z520i costs $1,980.
