The last I heard they were giving bridge addresses to friends within the country that were spreading them through their social networks (since china had blocked all the bridge addresses they were giving out online). That along with the obfuscation stuff was working.

China's deep packet inspection was pretty sophisticated though and getting worse (usually ramping up during political events). It'd be interesting to see an update, but I haven't seen a talk from Roger Dingledine or Jacob Appelbaum about it in a while.
