The new gestures let you swipe up to see the multitasking bar, swipe left or right to switch between open apps and pinch to go back to the home screen.
There's no word on whether the home button's wake function will be replaced by a gesture or if you'll have to rely exclusively on the iPad's sleep/wake button at the top of the device. Personally, I'm hoping for a knock-to-wake gesture.
It's not clear if the so-called iPad 2 expected in 2011 would lose its home button or if the rumored home button drop is planned for a later iteration of Apple's tablet. Although BGR says both the iPad and maybe even the iPhone could lose their home buttons this year.
Hardware Rotation Lock
If you were sad to see the iPad's screen orientation lock switch become a mute button in iOS 4.2, it looks like your prayers for the return of the screen lock have been answered. The Settings application in iOS 4.3 has an option to make your iPad's side switch a mute button or a screen orientation lock, according to MacStories.
The mobile hotspot option that debuted in Verizon's (VZ) CDMA-based iPhone is coming to all iPhone users with iOS 4.3, according to BGR. The feature allows up to five devices at once to use your iPhone's 3G Internet access. But this new feature will probably be added at your carrier's discretion, which means AT&T iPhone users may be left out in the cold.
One thing that hasn't appeared in iOS 4.3 beta, or remains undiscovered, was any mention of an in-app subscription model for newspapers and magazines. We'll have to see if that feature shows up in a later beta of iOS 4.3.
UPDATE: 9-to-5 Mac made another discovery in iOS 4.3 that appears to be references to the next iPad's highly rumored front- and rear-facing cameras. The gadget blog found four files referencing the camera, and images of what the camera shutter effect will look like on the iPad screen. The images were 1024-by-768, which suggests the next iPad may have the same resolution display as the current model.
