Hi! Recently I've been told by a few relatives that I am called something, for them, weird instead of my real name when texting them. It is communication through iMessage. The thing is that instead of my real name which they have in the contact, I am displayed for them, with a short name or nickname. You know, under the settings > contacts > short names.. The thing is, I am clueless in how Apple/their phones/ios or whatever, gets the information to use that exact short name. I haven't put it in somewhere on my own phone or theirs from what I remember. Where does apple get the information from? I know that I am called this on eBay but thats all I can remember for now. How come apple displays this shortname/nickname for my relatives? Does anyone know how this works? I know you can turn it off and if I turn it off on my own phone it just disables the function for my messages not "sending away my nickname"? Under my contact info in my girlfriends phone, it has, on one line "IM_SERVICE_NAME" and the nickname that i'm getting called, which is the problem. What is that? Please, help me. It's not embarrassing but imagine if the nickname was something vulgar.
