I have a Sony Ericsson w580i phone and would like to get wi-fi internet on it?

Does anyone know of an application or something i can download onto my buzz to make it wi-fi enabled?

I want to be able to get on the internet for free on it without buying a data plot.
and there’s no way i can modify it or hack it to be able to support it?
