Photos: Sony Ericsson unveils the W880i, K810i and others

The W610i Walkman phone is slightly thicker than the W880i at 14mm deep, and doesn't come with 3G connectivity. It does, however, come with a 2-megapixel camera with autofocus and an expandable memory slot (M2). Other features include stereo Bluetooth and EDGE (2.75G) connectivity. The W610i will be available later this year.
