Password forgotten/mistyped during setup
While setting up up my iphone of the first time, I entered what I wanted to be my passcode and proceeded through the other settings. I then switched off the phone while I took my SIM card out of the old phone, however when I turned on the new iphone, it doesn't recognise the passcode I entered before. I'm not sure if it was my error, or the phone's, but how do I gain access to reset the passcode? I had not connected to itunes/cloud beforehand.
I am a complete beginner to iphones in general so a step by step guide would be appreciated. Thanks!
