The Smart S100 is the next slimmest phone at just 7.7mm thick. The phone boasts a OLED screen (128 x 160), 2.0MP camera, and able to play MP3/MPEG files. It seems that this phone does not have the memory card slot. However, it has an interesting rotary format design keypad. The Smart S100 is not going to be available in all regions with only GSM 900/1800 network supported. No word on pricing yet. More pictures after the jump!
