The new iOS 4.3 release will officially support the 2009 iPhone 3GS, the GSM iPhone 4, third and fourth generation iPod touch, and iPad models. This leaves out the CDMA iPhone 4 as well as Apple TV (which is normally updated on its own, independent schedule).
The Verizon iPhone 4 was released using its own software build, labeled iOS 4.2.5. Other iOS devices remained at iOS 4.2.1, which was released in November. Apple subsequently updated Verizon iPhones to iOs 4.2.6 to fix a bug related to its new Personal Hotspot feature.
Apart from the brief exclusive of its Personal Hotspot feature, the Verizon iPhone is being updated separately because it uses a different baseband chip than other iPhones, requiring a separate firmware. Apple may be waiting for Qualcomm to deliver a specific update for the chip before integrating the new firmware into the iOS release for that model.
Apple hasn't announced a date for the Verizon iPhone release version of iOS 4.3, but it is likely to follow shortly after the initial release for GSM iPhones because the new build packs a variety of features and improvements.
New major features in iOS 4.3
The general features provided to all iOS devices by iOS 4.3 include Personal Hotspot (WiFi tethering), which Verizon iPhone users already have. However, there are also a number of other significant new improvements Verizon iPhone users will want, including:
â¢ Support for AirPlay video streaming by third party apps, as well as videos within the web browser or within the Photos app. Streamed photos also use slideshow transitions.
â¢ The ability to locally stream (without downloading or syncing) any content from your iTunes library via Home Sharing: music, movies, TV, podcasts, or audiobooks.
