How do I update my iPhone from the setup process
The iPhone is in the setup screen when I turn it on, however, when I get past the choose WiFi network it asks for an update before it can be setup, the same happens when I try to setup with my other iPhone nearby process. When I connect it to my computer the iTunes screen is just blank with the iPhone text in the middle and asks for a SIM card to be inserted.
The iPhone also doesn't recieve any reception even with the SIM card inside it.
Is there a way to update the iPhone?
