This version of iOS 4 is stable; I haven't had any problems with apps crashing, and the update itself went smoothly. AirPlay functionality is noticeably more reliable. This is important because, with the last update, there were times where I wanted to stream music to AppleTV but the AirPlay icon was missing, even though everything was set up properly. I didn't have any such problems during the months-long beta testing of iOS 4.3.

There are a couple of annoyances, though. First, the Camera app takes longer than it should to load. When iPhone 4 was released, the app launched instantly. With each update, that launch-time lag has grown. I've missed snapping some great photos because I was waiting for Camera to load.

Another annoyance: you can share photos or videos through Airplay in Photos now, but you still can't beam photos or videos through using the Camera Roll, which is where photos are stored within the Camera application. This seems like an un-Apple-like oversight. For instance, you can't take a picture or record a video and then beam it via Apple TV to your HDTV. Instead, once you record the video or image, you have to press the Home button, go to the Photos app, tap the appropriate album -- in Camera Roll, by the way -- navigate to the photo or video, tap the AirPlay icon, tap your destination and, if you're beaming video, press play. This isn't a deal-breaker, obviously, but adding AirPlay integration to the Camera app really couldn't have been that hard.

Still, it's , where you couldn't stream recorded videos or photos from your Photo Camera Roll at all.

As it stands, iOS 4.3 delivers needed security updates and several features that iOS device owners will like. Of course, speculation is already swirling about iOS 5, but this update should keep most users happy until that version appears. Version 4.3 may not clear the entire list of must-have iOS features, but it sure is .
