So here's the thing, I accidently spilled water on my iphone 4, although it has been fixed, it still get kind of "unstable ", sometimes it just suddenly shut itself down. Now I'm saving money for the new iphone 5, but I have a pile of important contacts saved on my watered iphone 4 and I'm so afraid that they'll be gone with the damaged phone right before I could get a new one. But if I can copy these contacts to itunes, then next time I'll be able to transfer them to the new iphone,right? Or just copy to computer? Any difference? Anyway, I just want the contacts to be backuped, any good idea? I don't mind if I have to pay for something but it would be the best if there's a free and easy way.Help me please.
