Ok thats good cos that's what I have too so I won't be giving the wrong advice! As far as I am aware that whilst the phone will accept you copying contacts from your Sim card, after that it doesn't have the same function as one of the older style phones where it could look in both the sim and phone memory. It only looks on the phone memory for the contacts.
So I have just had a fiddle with my phone to see if I could reproduce your fault and the only thing I can see is that a mobile number in your contact page has to be recorded as exactly that, not work or home or fax etc. I had previously stated that the mobile number needed to be first, but actually I think by me changing them I ensured that each number had mobile selected in the dropdown box beside it. So you need to go through your contacts and change all the numbers that are mobiles with the little drop down selector.
I hope that makes some kind of sense cos its not tripping off the fingers very coherently tonight!
Let me know if that helps.
