Yup! 9.3 was just released recently.
I know I updated last Monday when it was released. But I just got this update on my device.
Ahh it might be the newer version Apple released to fix the activation error on older devices.
I might be wrong
I thought about that. But I heard the update for older devices was only going to be available via iTunes.
That's what I would have thought, too. That's how they handled the 9.2.1 2nd release. Even then it's a full update at over 1gb, not just a "patch". Did you do it? Any chance you know the build number before and after?
