Buddy gave me an older iPhone. I want to use it just an iPOD. So I plugged it, let itunes download latest software and update it. Now, it keeps saying, no SIM card and i can't do anything. NO SIM CARD INSTALED - Insert a valid SIM with no PIN lock to activate iPhone. What does this mean? on the iPhone it goes directly to make a call - as if everything got reset. How do I fix this to allow me to use it as an iPod and Camera etc... Thanks Step by step help would be great. I'm not so good with the iPHONE/iPOD Stuff.
