Ever since the iPhone 3G came out, I've upgraded through the entire series and now have the IP6. I've always sold my previous addition either shortly before or during the week new phone debuted. When my new phone arrived, I would restore my previous backup immediately. Now, IF the official version of iOS 9 doesn't come out BEFORE the new phone debuts, it may be a problem selling my present phone with a Beta. And of course, I may not be able to "restore" my new phone if the backup is the present or future 9.0 Beta at that date. I assume the new IP will come with iOS 9, but the official upgrade version may not be available until later. I've done 3 Beta tests with Mavericks, Yosemite and now El Capitan, but never an iPhone beta. Do you think I'm making a mountain out of a mole hole? Thoughts?
