Free internet - Sony Ericsson K770i Purple 3G Camera mobile+256mb Cellular Phone

I dont think there is any good free internet that you can own. but you can try from this article: http://www.makeuseof.com/tag/how-to-get-free-internet-service-almost-anywhere/

There are many places that provide free wifi services anyway such as cafe, library or even random friendly neighbours that allow free access to their network.

Not necessary. Your notebook contains pre-installed windows essential security application. So it protects your computer. But if you using internet constantly on your notebook you need an Internet Security Software to protect and safe guard your information.

internet is never free, the internet depends on your network provider, and depends on what bundles you have, if you are on pay as you go its likley the internet isnt free unless you buy a bundle, if your are on contract its likley that you will have some free allowance to use the internet, but you should check with your service provider first if you are unsure as using the internet on your mobile without a bundle can be very expensive some networks charge upto £3.50 per mb

What do you mean list of free internet sites? You CANNOT get free internet. No such thing. As you have to pay the ISP or internet service provider who allow internet to your house through a coaxial cable to which you hook up a modem to then the modem to a router to get wireless internet for laptops. Please mark this is a solution if I helped. Thanks!
