Apple has today released iOS 6 beta 3 to developers. This is about three weeks after beta 2 was released.
It was just released, so it’s not clear what differences there are from the previous beta software. We’re sure they will be found if there is anything noteworthy.
As the release approaches (no date was specified, but Apple said it would be available this fall), we expect the updates to become more frequent, and a GM (Gold Master) to become available very soon before it becomes available to the public.
