how to transfer internet from your computer ( preferably mac)

you can't just transfer your internet from one device to another. If you have wireless internet, then you can pick it up on your mobile as long as you have the password, and you're within a certain distance from it. I can pick up my internet on my itouch from about 3 houses away from me. If you don't have wireless internet, then either go out and get a wireless router, or go somewhere that has it wireless. Loads of restaurants and pubs and coffee shops have free wifi, sometimes you just gotta ask for the password.
