I've done some searching and the only half answer I can get is that you can get iPhone Wifi to work if you have previously activated the iPhone with a SIM card, and then take it out. But is there any other work around? I am trying to get Skype to work on my old first generation iPhone over Wifi for here at the house. I have the iPhone 3G for my main use. Would it hurt anything to temporarily take that iPhone's SIM card out and put it in my old one, activate it, then take it out? Will that hurt anything? Thanks!!
