Use facebridge and twitbridge. Simply the best.
I've tried all of these and I still can't get around it
I'm a past customer of Witopia and Freedur. Witopia was ok for reading news sites but always slow for video streaming (youtube, iPlayer, Hulu). I saw lots of Freedur ads on expat sites and I thought this VPN is good. Freedur was faster but with very often interruptions (almost daily). Also the software was easy to use but full of bugs. It was a memory hog on my computer (used more than Firefox). Also it seems this company has really bad security practice as they were hacked a few times and customers information was stolen (by "big brother" maybe?)
A friend of mine invited me to HideMyAss - I got a 30 days Account. HideMyAss VPN is very easy to use, just like Freedur, but really much more polished than Freedur and with much more servers. Also HideMyAss is the fastest VPN I ever used in China. I was really happy during the trial and decided to go for 1-year (about ~$6.55/month). I really recommend it.
