Apple has released iOS 4.3, the update includes support for iPhone 4 GSM, iPhone 3GS, iPad, iPad 2, and iPod touch 3G and 4G, and Apple TV 2. iOS 4.3 brings AirPlay improvements, improved Safari performance, iTunes Home Sharing, the addition of the iPad orientation lock switch, and Personal WiFi hotspot for iPhone 4.
Download iOS 4.3
You can download and install iOS 4.3 by checking for updates within iTunes.
Alternatively, you can download iOS 4.3 IPSW directly from Apple:
iPhone 4 (GSM)
iPhone 4 (CDMA) not yet released
iPhone 3GS
iPad 1
iPod touch 3G
iPod touch 4G
Apple TV 2
iOS 4.3 IPSW is also available for the upcoming iPad 2:
iPad 2,1
iPad 2,2
iPad 2,3
If you are having trouble downloading the ISPW files, right-click and Save As or use a different browser.
The Verizon iPhone 4 CDMA model is expected to receive the 4.3 update later, although no timeline has been announced from Apple. Older iOS hardware such as iPhone 3 and iPod touch 2G and 3G models will not be supported by iOS 4.3 and are ineligible for the software update.
