Hi all, I just got my iphone 3G and I'm very happy with it Here are some newb questions: * My iphone is currently sync'd to my home network via wifi so it's all good. But what if I wan't to use 3G? Do i have to setup the 3G connection or it's all stored in the sim card? * Does "pressing the home button" quit the active app? Is it possible to run apps like Fring in the background? * My wallpaper is not showing. I'm in Settings -> wallpaper -> set wallpaper but it's still not showing, all I get is a black background. * Is it possible to sync a blue tooth keyboard to the iphone and use the keyboard to type instead? * What's a good iphone case? I prefer light and transparent. * When I add a movie to iTune, where abouts is the movie copied to? Thnx in advance.
