Like the title say, I tried to see if iCloud account would work on my 2G, but it did not work. However, my MobileMe account does work with mails, contacts, notes, and calendars.All sync fine. So I was just wondering will my MobileMe stop working on the 2G whenever I merge it with iCloud? Thoughts everyone?
