I have recently acquired the HTC Touch HD. I have a dual SIM card, and both numbers show up correctly in the "List of own numbers" within the SIM Manager program. How do I change from using Voice Line 1 as primary to Voice line 2 as primary?

I'm pretty sure there's no way of doing this from within the SIM Manager program. Does anybody know how this can be done?

All assistance gratefully received.
