So… no dual core, and the lack of RAM is a little dissapointing but the screen resolution seems alright, along with Voda and Telstra NextG support this seems like a good alternative to a Optus Mytab.
There are actually quite a few ChinaTab with 3G. Just scanned through BuySKU:
But yeah, none have dual core.
