I apologize in advance for asking what I suspect is a very basic question. I inherited an old iPhone 3 from my father. My goal is to use it to surf the web via wireless -- I have no desire to use it as a phone. I connected it to iTunes and did a "restore" to factory defaults, but the process came to a grinding halt with the message that I had no valid SIM card. What is the best way for me to proceed? The jailbreak tutorials I've found assume that one is starting with an operational, functioning iPhone, but mine won't allow me to do anything but make an emergency call. Again, my goal is to use it as, basically, an iPod Touch. I want Safari via wireless and not much else.
