Brief note on something cool I just heard that'll help you call home from China easier and cheaper than Skype or Pandaphone.
Check this out:
T-mobile's new cellphone plan gives you free calls from any wireless hotspot (they're also giving away wireless routers, so you can call for free from your home). But the hotspot thing is of interest to world travelers, since it uses the internet from wherever you happen to be in the world. If you have a cell phone in Belgrade, Maine, and stroll into a web cafe in Bahrain, Benares or (most relevantly)
Beijing, the call will still be
free.
I haven't tried it, so I don't know if it lives up to the hype, but it sounds pretty darn awesome.
