When I got my iPhone, all my contacts from my old phone magically appeared in my iPhone. How did this happen? Aren't my contacts stored on my SIM and on my old phone's memory? I was an AT&T customer already; did this have something to do with it? It was great that I didnt' have to import my contacts, but also kind of weird that it happened automatically. Did this happen to anyone else? I did a quick search on this forum and didnt find anything, so sorry if this has been asked already.
