I didnt want to go create an account on the Apple support forums to post this..and I figured someoen here will get it pretty easily. I have an iphone 5 with all my music currently on it. My iphone 3gs is sitting on a shelf at home, unused. Because all my peripherals have the old adapter, I'd like to use my old iphone as an ipod. The questions I have is: if I sync it to iTunes, will iTunes try to make it my primary device and change all the syncing settings I have set up for my iphone 5? If I am wrong on this, how can I make sure that all I do is update the tracks on my old iphone? Clearly there's a way for a person to have an iphone and an ipod in use with the same iTunes account...but I have not been able to sort out how.
