Just wonder what configuration I should get in a new Nexus to use in China. I want to buy a new phone. Should I get an AT&T or T-Mobile? The issue is the 3G in China. Also those who use it in China are you using 3G or EDGE? Which is cost effective? How will I get the 2.2 update? Will it come direct from Google? I do not want to manually get it as I am not good with tech stuff. Any other considerations for using it in China?
