Here's something unique from Nokia, the 7500 Prism phone, presented recently in China. It is designed in diamond style, as you can see on the photo, and has pretty usual specs, such as 2Mpix camera, microSD slot, a QVGA screen and a S40 OS (v. 5.0). All this with a diamond shaped keyboard.

The Nokia 7500 Prism was approved by FCC and will soon be available for purchase.
