First you have to download a Small program, Here:
http://www.megaupload.com/?d=BUZVD76F
After you have u2 Downloaded, extract teh files to a folder. Now open an internet explorer page.
Open u.exe.
When the little window pops up it shows a home button. Click thta button after about a minute.
It will go to a Japanese Page that is basically an Uber proxy, that cannot be blocked. If you do not run the program u2 howver, the school/buisness probably did block it.
If theres a program that says; New software found, do you wanna update?, click no and resume.
It will do a google search, opening a new page, and then you simply click the link. You could also just use the adress bar, in the new window.
EDIT* After you X the little window off, a golden lock will show up at the bottom of your page. Dont fear, that is just a little toolbar sorta, right click on it and go to homepage if you wish to do it again.
Credits: Credits go to a private friend of mine who lives in Brazil, he is one of the people who cracked the u2 software, this is version 8.5 i think and the newest version is 5$ (8.8).
If you skipped one of the instructions, the next probably wont make any sense.
If you need any help, or want to suggest a simple method on this, just tell me.
The yucky part is that most schools have gaminggutter blocked =\
