Its basically a bigger HTC G1. I still have my original G1 and those specs are similar except the extra ram minus the resistive touchscreen. Check you settings and go to about device/phone. It appears as though the firmware may be misleading "Android 2.1 Firmware 1.6"??? 1.6 is Donut and not Enclair.
