Hi, I got an Iphone 4s last week and this is my first experience with an iPhone. I had something disturbing happen to my contacts. When I first got the phone I transferred all my contacts over using the Verizon Bacup assistant app. It worked fine. Everything has been on the iPhone since last Friday. Suddenly this afternoon, I went to text someone and all my contacts were gone! Anyone else have this happen? Is there something I could have hit that would have removed them? I was able to just use the Verizon app again, but I'm kind of concerned that this happened to me. I've never had to use anything other than Backup Assistant on a phone before. So, another question, which is a better way to backup, use iTunes or iCloud? Thanks for any help!
