I just got an iPhone 5 and want to setup my old iPhone 4 exactly like my new one. I use the 4 as an iPod. I know about setting up two different libraries in iTunes but I want them the same. Thing I'm worried about is if I hook up the 4 iTunes will make a backup of it. Just wondering if there is an easier way instead of copying the 5 library and making new one for the 4. Thanks in advance.
