hello, I am using an iPhone 4 iOS 4.2.1 when someone calls me I can not see the name, only the phone number appears. I even cant see the name in last calls screen. Only phone numbers there. I put 00 infront of the number nothing changed. Then changed it with +. But still same. Only the Last Calls screen is fixed but incoming calls are still only numbers. And it looks crazy to change 600+ contacts only for a half fix. Can you please help?
