WIFI HELP!!! please urgent!
 

I'd been trying to sort this out for the past 6 months but didnt come up with a solution. alright. it goes like this
I have a blackberry pearl 8120. I want to browse internet through the wifi available on campus but they say that u need to configure/enter the proxy and port as 10.2.20.16;8080. now where and how can i do that?
any help would be deeply appreciated.
Thanx
