Well, that was a wee bit quicker than we expected, but Apple has released iOS 4.3.3 to the public.
Although the update was initially said to be released sometime in the next few weeks (it was about a week ago when they stated this), it looks like Apple has finished testing and has opted to release iOS 4.3.3 ahead of schedule.
Why the rush to release such an minor update? It's just a sneaking suspicion, but it might have something to do with the bad press that Apple's been receiving as of late due to a certain location tracking bug...
