Sony Ericsson is rumored to release its first slim clamshell. It will be called Z660i. The phone will be just 14 mm thick, reports the source. It features UMTS support, a 2-megapixel camera and A200 platform. Probably the announcement of Sony Ericsson Z660i will take place today (no official confirmation). Meanwhile a SE fan has offered his version of this ultra mobile clamshell.
