>From the design-side, the SIM PIN will use the numberpad that we use for
the passcode device lock. And as Tony said, it will be displayed
immediately on boot if it is required, with a prompt for the user to 'enter
SIM PIN'.
If the user chooses to dismiss the prompt, an indicator will be shown to
let the user know the SIM is locked.
