I want to verify that iPhone 4s' with the caller id with name feature on their plans work fine, since my carrier is claiming it's a phone issue not a carrier issue. How to test: when a caller that is NOT in your contacts calls and the name associated with the number is shown instead of just the number then it works! If you only get numbers, never names and you know you have the feature in your plan with your 4s then please say so. I want to see if any 4s owners with this feature have it working properly on their phones. Carriers I know who definitely have this feature are; Fido and Rogers in Canada. Anybody who knows other carriers with this feature please be free to post in this thread.
