I use my college internet and it blocks lots of web pages, how can i by pass this pain? i use my own notebook.
alsoe it doesnt let me use pidgin.
Try out Tor:

Once you managed to connect to the tor network, there is no possibility for them to restrict you.
Perhaps you want to set ClientOnly = 1 in your torrc since the college network usage conditions might not allow you to run server-like services.
i downloaded the tor browser but that just allow me to use the tor browser, it doesnt let me use pidgin. it asked me questions like if i need a proxy, like which ports are not blocked. if it use a firewall... now i can use the web freely but not pidgin
You can use smth like Jappix with TorBrowser. Other way is to install TOR and use it as proxy (Pidgin supports SOCKS proxy), or just start pidgin as "torify pidgin".
how i install tor for being able to use it as a proxy? because i just se the tor browser in the tor project web
If you can reach the blocked sites by their IP, then you could just use another DNS provider. However whatever technical measure you use, circumventing some censorship measure might get you in hot water with the management...
VPN?
If tor is a service, listening on an an ip port, why use tor browser bundle? Can't one just set 127.0.0.1, port 9050 as a proxy server, and connect internet apps through it?
Tor is the best choice you have right now. Using Tor Browser Bundle and Torbidy (a Thunderbird extension) you can use both browsing and email in freedom AND privacy. However, IM is a problem for a long time. You can try to use TAILS, which has pidgin incorporated, but there is a danger of:
a) leaks;
b) not working anyway;
Pidgin apparently was very hard to get to work with Tor because is not a matter of simply sending the text and receiving it back. It has to access the servers of your IM account, use authentication, support OTR (for safety reasons), etc. Roger Dingledine said that they are working into incorporating IM into TBB but it will take some time. For now, there is no perfect solution.
Maybe you can get the person you want to talk to to use a web based chat room...? That way TBB would solve it. Is not a perfect solution anyway.
