SMS-Sender name not being picked up from contacts

[snovvman]

I have a contact entry with a phone number and name. When I now receive an SMS, the message shows only the phone number of the sender, not the name of the sender.

This used to work, but now both the inbox and sent items show the number rather than the name. If I send via contacts, the item will show the name. When the recepient responds, only the number shows.

The event that, I think, caused this was a hard reset and a restore (via Sprite). Is there some registry entry that needs to be hacked/corrected?

Has anyone else seen this problem?

Thanks.
