With the imminent release of iOS 10, I'm wondering if I should upgrade my iPad 2 to iOS 9 now. Specifically, I'd like to know if I will still be able to do that after iOS 10 is released? (Currently at iOS 7)
I know that I'll be forced to upgrade one day, as some app I like won't support iOS 7 anymore, but I'm also aware that it will make my iPad even slower, so I'd like to hold off as long as possible. But, I don't want to end up in a situation where I can't upgrade to 9 anymore, e.g. because Apple stops signing for 9 after the release of 10?
