Apple released their mobile software update - iOS 4.3 for iPhone, iPod Touch & iPad. Most importantly this update will remove your untethered jailbreak! Wait for iOS 4.3 support to be added to greenpois0n or another tool is released before upgrading your iDevice! But this update leaves some devices behind...
These are the supported devices
iPhone 3GS, iPhone 4, iPod Touch 3g/4g, iPad & iPad 2.

This update adds many new features & increased speeds for Safari mobile browser. Added features include new Mobile Hotspot allowing you to share your 3G data connection with multiple WiFi enabled devices, but you have to have a tethering plan from your carrier to use this feature.

This new iOS update also adds increased functionality for the AirPlay feature. Now allowing you to play video shot from your iPhone, iPod Touch 4g & now iPad 2, in addition to songs from your iTunes library to your Apple TV2 connected to an HDTV. Another streaming feature added in iOS 4.3 is iTunes Home Sharing. Accessing your iTunes library from any Mac or PC in your home on the same WiFi network. allowing streaming any song, podcast, movie or TV show in your iTunes library to your iPhone iPod Touch or iPad without downloading or syncing all over the airwaves!

Now surfing the web on iOS 4.3 mobile Safari is blazing fast with the new Nitro JavaScript engine. It runs JavaScript up to twice as fast as in iOS 4.2.1. And feature rich interactive sites with videos & animations load with increased speed & performance.

I saved my personal favorite for last. This feature requires an additional accessory to use that's not even out yet, but Apple's 30-pin to HDMI connector allows mirroring from iPad 2 to any HDTV in full 1080 HD. Anything from video to photos to apps all mirrored in Full 1080 HD on any HDTV with an HDMI port! It will be available as soon as the iPad 2 goes on sale & is also said to work with the iPhone 4.
If don't need a jailbreak or unlock you can upgrade your iOS firmware version in iTunes by checking for a software update. Go to iTunes, plug in your device & select *Check for software updates*
