Forgive my ignorance on this, but my wife and I both upgraded to iPhone 4 phones. I have a great condition iPhone 3g that I'm going to sell. My wife's iPhone 3G is missing the vibrate button on the side, so I thought about just letting the kids use it as an iPod touch to play games and such on. Can I effectively do this by syncing to iTunes for application updates and get applications on it without having to have it on a network at all? Or will it still even connect to my home network? In that case I could just keep using it to connect via wifi to the app store. Thanks! I'd rather have the kids drop or accidentally destroy an old 3G without a vibrate button than to accidentally damage or destroy one of our new phones.
