Hi, all, embarrassing situation here, looking for some guidance.
My girlfriend has an iPhone 4S, which until a short while ago was running 5.1.1. Her desktop OS is Leopard 10.5.8, and she is running iTunes 10.6.0.
When she plugged in her iPhone to update to iOS 6 via iTunes, we got a confusing message: iTunes recognized that there was new iOS software, but when she clicked she got a dialog box saying that *iTunes* was completely up to date. So she just downloaded iOS 6 directly to her iPhone via Software Update.
Now we're in a bind that we didn't realize would be a bind. iOS 6 requires iTunes 10.7 to sync. But iTunes 10.7 requires OS X 10.6.8, which she doesn't have. We don't wish to upgrade her to Lion or Mountain Lion, due to some legacy PowerPC apps. So now we have a phone that cannot sync with her desktop. She has an iCloud account, but unfortunately was not backing up to the cloud; she was backing up to iTunes. iTunes now does not recognize the phone.
Now, *I* have Mountain Lion, and iTunes 10.7.0. When I plug her phone into my computer, it's recognized and I have the opportunity to restore to factory settings. But I would want to know what we're in for. I could back up her settings to my computer, but I don't have her music library or apps. If I restore her phone to factory settings on my computer, then plug it into HER computer, will she be able to restore one of her phone backups that resides there? Will that include the sync settings?
Can someone give us some guidance on what to do in this situation? Thanks in advance!
EDIT: And of course the missing piece of information was that by this chain of thought, iOS 6 isn't compatible with Leopard, or is at best poorly compatible, which is something we should have researched beforehand.
