iOS 4.3 has arrived, and with it a number of improvements to Apple's mobile OS. The biggest news is that the App Store will now recognize if you've previously purchased an app, and now iPhone 4s have access to the Personal Hotspot feature. Along with a bunch of bug fixes, Safari has also gotten a nice speed boost and you can finally reclaim the orientation lock button on the iPad. Fire up iTunes for the update, and check DownloadSquad for a
