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. Since iphone 5 is coming soon, I think I'll wait till then to get a new one.However, 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 use Dell PC with Win 7 system.I don't mind if I have to pay for a tool but it would be the best if there's a free and easy way.Help me please!!
