I have two accounts and a new Thunderbolt phone for one and an old beast for the second.
I have a contact set up on the TB for the second account (my wife). When she calls the Android the call is shown as 'Unknown' rather than the contact information I have set up.
If I call her using the contact in the ThunderBolt her phone knows its the TB as it should. I have check our account and neither phone has caller ID blocking. I enter phone numbers as 10 digits (no spaces, no par ens, etc).

Try checking location of the number being stored on your device... Some Contacts on SIM does not display correctly with caller if.. Make sure contacts are placed in Google...
Import contact from SIM card
