New iPad3 owner here........ I've synched with my PC/iTunes several times to install apps and songs.....worked fine. I notice there is an option to turn on synch with WiFi.....how does this work? Any time iTunes is open on the PC and the iPad is on it will synch? Can I tell it when to synch or does it automatically? I like this idea but I don't want it synching when I'm surfing so I kill the bandwidth. Thanks..
