I have a jailbroken 3G running 3.0 that was previously (a long time ago) synced to my computer. I also, in the past, have connected/synced several other Iphones to the same computer. For some reason, when I connect my current phone, it doesn't recognize it as having been connected/synced before (even though it was). Itunes gives me two choices: Set up as new phone, or restore from other phone choices. My question is this: I just want to backup what is on this phone. I do not want to restore fom another save, or erase anything on my current phone. Just back it up. So, how should I proceed. Will "Set up as new phone" erase everything, or will it do what I want?
