This is probably a dumb question but I am using this new IPAD2 for a specific business purpose and the area I will be using this has spotty internet service to say the least. All I need to do is to play movies through I-Tunes. That is it's only functionality for me. So my question is, if the videos are already downloaded onto the IPAD, does I-Tunes have to connect to the internet to play them? Basically I'm trying to determine if I need to get the 3G? I only want to use this to play video and nothing else. Will it play without wifi/3G? Thanks guys!
