[I_Am_Wrong]

so I just got a korean language Cyon cellphone for free from a friend. I've managed to figure a lot of it out, but I can't figure out how to change the name it shows on the first screen, how to delete what looks like his past received calls and phone book. Also, how do I enter my phone numbers? Any help with this would be much appreciated. I don't really want to bother my buddy cuz he's insanely busy with intense shit right now and it was already super nice enough of him to give me the phone for free. thanks in advance.
