I have just got a 9700 and whilst I think that it is a great phone I am having the same caller display problem. I had only had the phone for two days before I noticed the problem and a week later it is still happening. All my numbers are in contacts and I have not downloaded any apps.
driving me mad though!!
Cheers

p.s. does any one know how to get missed calls to show in the call log along with the made and rec'd calls by just pressing the green button? At the mo I only have the made and rec'd calls.
I just updated to the latest beta and my ongoing problem has now gone away. Recent builds have all had this bug it seems. I've been living with it for over a month, but no more!
