How to change my caller I.D. For my iphone 4s?

Recently, I called a buddy of mine and instead of it saying my name it said something like karma or coral and it was me when he answered. I was just curious if there's an app or software for that for iphone 4s's. If so, can you refer me to it?

You gotta go under contacts and edit the name. Seems like someone changed your buddies contact names.

Other than changing the name assigned to the number in the Contacts app there's no way to do that.

  • Why is my iPhone 4 changing around caller ID pictures? Recently my iPhone has started changing around the caller ID photos of my contacts. Not sure why and wondering if it might be a bug? Has anyone else had this problem and is it something to worry about?
  • Which app can I use to call and change the caller ID? I've seen my friend use this app that he calls but he can change the caller ID, I remember he called someone and he put 911 as the caller ID. I would like to know what is the name of that app for the Apple Store / iPhone / iTouch.
  • When you Block Caller on iPhone, does it completely block them or do they show up as Unknown? I routinely "Block Caller" telemarketers, so does using the iPhone "Block Caller" option block all calls, or will the calls still come through and just show up as "Unknown"? I've received a lot of "Unknown" phone calls lately, so that's what I was attributing it to.
  • What's the difference between an 'unkown' caller and 'no caller ID'? This unknown number keeps ringing me, and i thought if someone blocked their numbers (on iphones) it comes up as no caller ID so i'm not sure if it is still a blocked number or a number that can't come trhough. But when i answer nobody speaks and they've rang one of my friends so its not a scam phone call also they don't speak at all so if it was a company of some sort they must of spoken so its probably a prank call but i wanna know the difference to make sure.
