This is just a quick heads up that Apple has now released the iOS 4.3 GM firmware to developers. Now obviously as this time it is just a development release, however on March 11 (the same time Apple releases the iPad 2) the iOS 4.3 firmware is going to be released to all iDevices except the iPhone 3G. The iOS 4.3 firmware will bring with it multi-gesture controls and possibly even updated applications like photobooth. iPhone unlockers and jailbreakers must stay away from updating to iOS 4.3 their devices, as Apple have fixed the exploit used in greenpois0n, limerain, redsn0w and PwnageTool will not work on this build. Read on foe the iOS 4.3 changelog.

• Option to use Side Swtich hardware button on iPad either as a mute button or as a rotation lock.
• Personal hotspot on iPhone 4 GSM models
• Option to cancel the download of an app at any time
• Safari Improvements by introducing nitroJavaScript engine
• iTunes home sharing
• AirPlay improvement
• Support for FaceTime on iPad 2
• PhotoBooth for iPad 2

I personally think this version of the iOS 4.3 firmware will be the largest update to the iOS 4.3 generation. What do you think the iOS 4.3 firmware will feature?
