I have this weird problem on my 3GS. This is what happens: 1. Someone calls me from number not in my contacts. 2. I go to my "recents" and click the arrow, and then "create new contact". 3. I type a name (Lyle) and click "save". 4. In "recents" the number now shows up as "Lyle", everything seems ok. 5. In the "contacts app" Lyle does not exist. Therefore also does not sync with mobileme. If I add a contact in the contact app itself, everything works fine.
