iOS 4.3 Brings Mobile Hotspot, New Multi-Touch Gestures And Hardware Rotation Lock

Today, Apple seeded the latest Beta version of iOS 4.3 to developers for the iPhone 4, iPhone 3GS, iPod Touch 3G/4G, iPad and Apple TV 2G. This new version of iOS brings quite a few changes including mobile hotspot. The Personal Hotspot’ feature was first seen in Verizon’s recently announced iPhone 4.

iOS 4.3 also brings in support for AirPlay for third party applications, new multi-touch gestures, a new font Noteworthy’ and iAd Full screen banners.

iOS 4.3 also includes new four or five fingers based multi-touch gestures. A four or five finger swipes left or right will allow users to switch between running apps, while a swipe up or down will bring up the multitasking bar. A pinch on the screen will bring users back to the home screen.

Below is the video showing the new four or five finger gestures on iPad running iOS 4.3 Beta-:

One of the most important changes in iOS 4.3 is the ability to change the Side Switch’ to either mute the device or lock its orientation. Apple had change the side switch orientation lock function to mute the device and was flaked for it. I guess Apple heard all the whining and prayers of their iPad owners and provided users with the mute or lock switch option in the latest version of iOS.

Also with the release of iOS 4.3 Beta 1 and the introduction of new multi-touch gestures, rumors have started floating that the next generation iPad and iPhone won’t sport a Home’ button. In fact, Apple employees are already testing the next generation iPad and iPhone without the Home button.

Here are the steps to jailbreak your iTouch device using Redsn0w 0.9.6b4 :
