You have to admit that chinese's skill is getting better, including all those making-it real fake phones. Now they are able to pack everything in a phone with 7.7mm thickness.

Other than the slimmest Samsung X828 6.9mm phone, Smart S100 is the next slimmest phone at 7.7mm. It has a OLED screen (128 x 160), 2.0 megapixel camera and able to play MP3/MPEG files. No mention on the internal memory though, the memory card slot seems like not available too. This is also another keypad design in rotary format, while the center d-pad let you navigate through the menu. The Smart S100 is not going to be available in all regions with only GSM 900/1800 network supported.
