A few minutes ago, Apple seeded the final ‘Gold Master’ version of iOS 4.3 to its developer, about a week before its official launch day, March 11. The new operating system is available for download on the iOS Developer Center website, and is compatible with iPad, iPhone 3G/3GS/4, as well as third and fourth generation iPod touch. The seed is labeled build number 8F190, and introduces several new features, such as personal hotspot support, iTunes subscriptions support, and AirPlay video streaming for third-party apps, to name a few.
While the beta version of iOS 4.3 used to support new, 4/5 fingers multitasking gestures on the iPad, the feature didn’t make it into the final version of the operating system. The software is of course fully compatible with the iPad 2, and all iPad 2s sold on March 11 will come with the operating system pre-loaded on the device. Also, Apple just released a new version of one of the tools used by iOS developers to build their apps, Xcode. Note that this new version is a Gold Master as well, and replaces the previous Gold Master, that proved to be unstable in some cases.
Apple encourages iOS developers to download the new version of iOS and Xcode to test their iOS apps and make sure they are fully compatible with the upcoming operating system.
