Damn. That sucks. I guess i will learn from your experience.. no upgrade for my daughters ipad.. and I should probably go ahead and sell it with iOS 7 on it. Then upgrade to a newer model. Yaaaah. more money for Apple
I see Chris Breen says this on the subject.
This one fails the "What would Steve do" test. Under his leadership Apple routinely stopped signing older versions of iOS (the policy was, in fact, instituted when he ran the joint). Yes, even when older devices struggled with a new operating system.
As we've said over and over, if you have an older device, wait to update until you've heard reports of how they perform with the new operating system. That way you can update based on the experience of others.
