I checked from internet and known the China iPhone No.4, which is the cloned of iPhone4. It's much cheaper and the appearance is almost the same as the original one. "Its also very thin too, only 9.3mm at thickness. It gets a 3.5 inches 960×640 WVGA touchscreen, dual core processor and a 5.0M Pixels camera with flash. Its based on a MTK platform, and gets Wi-Fi connectivity for you to access the Internet. "
