I have an iMac running Snow Leopard. I haven’t upgraded to Lion because I still have important files in AppleWorks 6 Draw format, that I can only open with Rosetta. My iPhone 3GS runs iOS 3.1.3, and I have a MobileMe account. I’m trying to figure out how to keep Rosetta compatibility (will Mountain Lion have Rosetta?) and still move to a newer iPhone, and get iCloud. I need to know what to do and in what order.
