In reply to frankcp87:
The Chinese are actually pretty hopeless at blocking internet sites, the restrictions are very easy to get round, you can even get BBC news! The Iranians could teach them a thing or too, as could the Uzbeks. www.f1.proxymice.com worked for facebook for months in China before they blocked it.
To answer your question, you want a proxy browser, not just a proxy for a particular site, then you can access any site you want in total privacy. I've found the Tor browser to be excellent:
https://www.torproject.org/projects/torbrowser.html.en
It's free to download and it's worked in every country I've visited with heavy internet restrictions, including China when I was last there (9 months ago) and Iran, who are much better at blocking sites (8 months ago). I don't know much about computers, but it does seem to slow your browsing speed a bit, so I only use it for blocked sites. You may find their site blocked, if so send me a pm and I can e-mail the programme (it's tiny).
Hope this helps.
