Here we go, everything you need to know about iOS 4.3 for iPhone and iPad in just 5 minutes -- orientation lock/mute switch toggle, multitouch navigation gestures, and Wi-Fi personal hotspot.

If you don't have a lot of time but do have a lot of curiosity, just hit the video up top, sit back and watch, and then let us know what you think in the comment below.

Note: If you're running iOS 4.3 and you can't get the multitouch gestures to work, try connecting to Xcode and hitting the "use this device for development" link. That should make the toggle pop up in Settings.

Now iPhone will be getting those gestures and iPad that hotspot... right?
