Apparently the Black Diamond will be available in 2007, not from Sony Ericsson but by a company called VIPN. Initially only 5 unique numered pieces will be available for the unbelievable price of $300,000.
With regards to the specifications, don¡Çt expect anything remarkable for your money. It will have Quad-band with Wi-Fi, an Intel 400Mhz processor running windows mobile 5, and a touch sensitive 2'' screen. It will also include internal memory of 128mb and will come with a 2Gb SD card for external storage, plus a respectable 4 Megapixel camera.
The designer Jaren Goh has used some pretty impressive materials for the build, featuring titane with polycarbonate, mirror-finish cladding and diamonds.
