Hello, I haven't yet put the GM on my iPhone 5s and iPad 4. I know that when you first install iOS 8, it gives you the option to upgrade to iCloud Photos and iCloud Drive. I also have an Early 2011 15" MacBook Pro running Mavericks. I have heard that the iCloud upgrade is not reversible and that you lose access to your iCloud Documents & Data until your Mac gets Yosemite installed onto it. Photos are not a big deal to me as I don't use photo stream, therefore I have already imported everything. Is it safe for me to go to the GM on my iOS devices? This is the only reason why I am even considering waiting for the public release. Which also seems fishy, because when it's released to the public next week, won't users lose access to their iCloud Documents & Data when they upgrade, until Yosemite comes out? I plan on starting fresh on my iPhone with iOS 8, so I'm also wondering if skipping the iCloud upgrade and performing it at a later time is a hassle. If it is, then I'll wait until the public release to do a restore and upgrade my iCloud at that time. Thanks in advance for your thoughts!
