Help with transition to iCloud
Specifics: I have a Mac Pro Dual Core Intel Xeon, 5 GB RAM on OS 10.6.8, using MobileMe. My email is delivered through Mail via a POP account. I don't want to upgrade to Lion, but will upgrade my iPhone to IOS 5. Currently syncing through iTunes. Can I use iCloud? Sync Calendar & Contacts? If I don't switch to iCloud, can I continue using iTunes to sync my info? Just need a little direction. Thanks!
