Old, Old,,,Old iMac sync to iPhone5?
So, I just bought an iPhone 5 and I noticed in the tech specs that the iPhone 5 requires OS 10.6 or later to sync with iTunes. I have an old iMac that can only be upgraded to 10.5. Mine is as far as it can go, 10.5.11. Am I right in thinking the only way to get all my music, apps and contacts and bookmarks,I.E. everything that's on my 3rd generation iPod to my iPhone 5 is to back up everything to the iCloud? Then when I get my iPhone 5 complete the setup assistant and back up from iCloud?
