OK, there's plenty of threads on the internet giving help/instructions on this. But none I can find that deal with the implications of Lion and iOS 5/iCloud. I have an iMac that's about 2 years old. I've now got a Macbook Pro as well. I'd quite like to able to sync my iPhone with the Macbook Pro. But it's tied to the iMac. Is there any way I can sync the iPhone to the new Macbook Pro without losing App data, settings etc. I've got all my music, TV shows, movies, apps backed up on a portable hard drive. So it really is just the app data I'm worried about keeping. I understand the Library path has moved in Lion (that's where the iPhone backups are kept right?), iOS 5 brings into play automatic wireless syncing and iCloud backs up iDevice content. Do those factors have any impact on the best path forward for me?
