I just changed provider, and want to change default/given SIM PIN and unlock the SIM card, but the whole preference card is lacking its data and does not respond to taps.

Only a few places does a tap trigger a visual response (the Reset Voice Mail Count button, Manual Settings, Data Usage and 3 blank lines above), although nothing more happens.

Due to this issue, Battery Monitor ain't able to do it's morning magic either. I have to turn the phone radio off and back on so that the phone asks for the SIM PIN.

Any ideas on what to try, except doctoring?!
