Well my D2G was just over 30 days old in my hands and I took it to be used in China. I went with Verizon Global Plan with a data plan. I made two calls one in Jilin and in Shanghai, I couldn't tell the difference and my parents didn't notice any difference in the call quality. My primary use of the phone was the data. Initially I had no problems when I landed in Shanghai. But in Jilin I couldn't get a 3G signal and was stuck with 1X (edge I think). First of all, the most annoying thing about this phone overseas was the roaming warning. Every time, the phone is powered up or goes into roaming, the phone asks you if you want to go to roaming mode, if you refuse or say no. You will loose your network connection with the Internet.
While I was using the 3G network in China, I had access to everything I had in the States. Yahoo (Mail/Chat), Google (Mail/Latitude), and even Facebook, which is normally blocked in China. I verified this when I tried going to use the hotel's wireless - I couldn't get into Facebook.
Aside from a few hard reboots and annoying roaming messages, the D2G worked as advertised. China uses both CDMA and GSM. From what I can tell the phone itself works fine. In some places, I thought my connection to the internet was as fast as my wi-fi.
