The update came a bit later than Apple intended due to an issue fixed by last night’s iTunes update, but the company just released iOS 4.3 for the iPhone, iPad, iPod touch and Apple TV. BGR exclusively revealed the change log for iOS 4.3 in January, which detailed most of the changes users can look forward to in this update. The most notable addition is Apple’s new Personal Hotspot feature which is now available on GSM versions of the iPhone 4 in addition to Verizon’s CDMA iPhone. Another highly anticipated feature now available in iOS is AirPlay support for third-party apps. Of note, this update is compatible only with the iPhone 4, iPhone 3GS, iPad, Apple TV and the third and fourth-generation iPod touch models. Earlier iPods do not have access to iOS 4.3, nor do the original iPhone or iPhone 3G.
