I know there is others, but this one is a true one.
Requirements:
You don't need your computer at home on, or any of that.
No remote desktop
No having to go to a site
Just downloading something.
Guide:
1. Go to http://gpass1.com/download/GPass.exe and download Gpass. Gpass is a proxy client in which is used by many people in China to bypass their blocked crap due to their crappy government.
2. Install the program and start it up.
3. Once installed, it will come up with your default browsers in which you click one. Eathier double click or hit Launch. It will then open a new window with this allowing you to be proxied up.
4. Once opened freely go to any site you want and it should work 100%.
Tip: I advise not sharing it with all the kids who don't know anything about computers but leeching off those who do. Thats normally how stuff gets blocked/fixed.
