Any apps that can bypass China's censored internet?

view story

http://forums.androidcentral.com – Hello community, As many of you know (if you haven't heard), china is pretty restrictive on their internet world. Not really that strict, just most of the sites I use, like youtube, facebook, are blocked in china. I plan to visit china soon, and I really want to download an app that can bypass china's censored internet (or proxy, etc). Are the any good apps that can like, I am not sure how to really explain, bypassing their internet, and they can't detect me what I am doing on the internet? Thanks. :) (HowTos)
