I just updated my Mac to Yosemite. During the update a new iTunes was installed. Now when I connect my phone it wants me to set up my phone only allowing a restore from backup or set up as a new phone. However, I don't want to do either. My last backup was a while ago and I've got quite a few new things that I don't want to lose. Setting up as a new phone is out the question. What can I do?
