Caller ID not showing names on BlackBerry

I have also been having this same problem with my 8330.
I have found a solution to our problem. The above poster is correct that if the phone is locked you can not see the name of who is calling but only the number.
To fix this go to options => security options => general settings => then go down to "Include address book", for this option select NO. This is what is preventing the phone from showing you Contact names on incoming calls while the phone is locked!
