I just got a new 5s and want to activate it using wifi, but I need the phone's mac address to do it. When I turn the phone on it goes into its initialization sequence and I can't get to the "settings" where it's located. My router filters mac addresses for connection permission so I can't connect. I could disable it, but I'm not going to do that. Is there any "trick" to sidestep the initialization sequence and get to the settings menu? This is my first iphone ever.
