I'm running an older MacBook with Tiger 10.4.11. And I've had a dot Mac account and email for almost 5 years now. If I don't upgrade my OS will I lose my email?? As I understand it, iCloud will only work with OS Lion. Also have an old iPhone 3G, OS 4.1 on which I can't update the OS without a newer version of iTunes (which I can't update with my older version of Tiger!). Will that give me the same problem?? Sorry if these questions have been covered elsewhere, I've searched some and didn't find these specifically answered. Thx for any help!
