I'll be getting and iPOD Touch soon, and I want to be absolutely certain that I'll be able to use all of its internet-related functions. I know that the device uses "Wi-Fi" technology, but is that only accessible in specific areas? I'm looking to be able to use inside buildings (home and friends' houses in particular). I really want to have to purchase any additional hardware or anything, but of course, any and all answers are welcome. Thanks!
