your laptop? i have a laptop but no way to get online, so this is music to my ears to hear i can hook my iphone up and use it as a modem....question is how do i do this? and does it cost extra? i have unlimited data plan on my iphone by the way...also could anyone tell me how to use wii-fi, every connection (even mcdonalds) asks for a security code, how do i use this too?
