I think this is because the number isn't tied to any of the contacts on your phone. Add the number as a new contact, give it a name and hey presto.

It worked for me anyway.

 

Weird. This must be something unique to Android. Every other mob I've had picks up contacts from the sim without a problem. I've never quite got my head around the Android way of handling contacts.

Glad you got that sorted

 

I rebooted the phone and it reverted back to normal showing names. I didn't know Microsoft had a hand in Handcent and the Android OS.
