I though I'd post this as I can't be the only person who's phone shows the wrong phone number in the settings? In my case I ported my old phone number to my new sim, but the phone (HTC Desire) always showed the old number.
I've just spotted a free app on the Market which allows you to edit the phone number shown in your settings, it worked a treat on my Desire.
