Hi there... I tried to back up my wife's i phone 4 with i tunes. It asked me if i wanted to start new or back up from existing account. I chose the existing even thou it was over a year since i did that... it never warned me about loosing information but when it was finished it went back to how it was at the last back up and all the most recent photos and everything seem to be lost .... i soo hope someone can help...
