I currently have a iPhone 4 that I sync with iTunes running on a PowerPC G5, with OS X v 10.5. I'm getting an iPhone 4S tomorrow and I want to transfer contents of the 4 to the 4S and in the future sync my 4S to iTunes on my MacBook Pro, currently running Snow Leopard, but I'm going to upgrade that to Lion. This is my plan, but curious if there is a better way to go. 1) Perform another backup from my iPhone 4 to the G5. 2) Activate the iPhone 4S with iTunes on the the G5 to get contents from the iPhone 4. 3) Sync the iPhone 4S with iTunes on my MacBook Pro running Lion. Are there any problems first activating the 4S on an older OS X, for any reason, specifically getting and syncing with iCloud?
