I have received a Android 2.2 OS 10.2" newest tablet pc WIFI 3G Camera HDMI 1GMHz, DDR 512, RAM 4GB from China. When I plugged in through a USB cable, it clearly shows 2.5gb hard drive, and unlike a normal pc I could not tell what system it is running from. Is it really a 1GMHz, DDR 512 RAM, how could I find this out? The status in the setting does not show all these, although it does state that it is Android 2.2 however. Could anyone help, please?
