I've just switched my phone number from o2 to Orange, as I've started a new contract. It's working fine, except that the "my number" thing on the call log page is still showing the temporary number I had before the porting took effect.

Does anyone know how I can change this?

Many thanks,
Ed Ludlow

Usually, it takes 24-48 hours for that to change. However, you can manually change it by going to Options >Advanced options >Sim Card >Highlight the phone number and hit menu key and select "Edit Sim Phone Number

Options, Advanced Options, SIM card, Press Menu button, Edit

I guess John Clark beat me to it.
