How would you tunnel through GFW?
cwan: I use witopia.net - great service - but make sure you get the more expensive ssl package (and play around trying the various nodes).  As others have said, it is truly the best $60 bucks I've ever spent if you're a frequent traveler in China.  I use it to watch hulu, youtube, facebook, etc.  Sometimes it's a bit slower than I'd like but I often find that using it I can get foreign sites faster than even going direct.
