A few minutes ago Apple seeded the third beta of iOS 4.3 to developers. It’s available now in the iOS Dev Center. Build number is 8F5166b . Updated versions of the iOS SDK and Apple TV pre-release software have been released as well. The release comes after nearly two weeks after the previous beta; iOS 4.3 beta 1 was seeded to developers on January 12. iOS 4.3 is expected to introduce a rather small set of new features like AirPlay video streaming for third-party apps, HTTP live streaming statistics and full-screen iAds. In the developer betas Apple also enabled support for multitasking gestures on the iPad, although the feature won’t be part of the public release of iOS 4.3. The software update has also been rumored to carry support for the iTunes subscriptions that will power The Daily, but no references of such functionality have been found in the SDK so far.
Last week, several reports indicated that Apple is already accepting iOS 4.3-compatible apps in the App Store. We will update this story as we find out more about the new beta.
Update: We did a little bit of digging in the latest beta and, interestingly enough, Apple has removed mentions of Imagination Technologies’ SGX543 GPU architecture (which supports multi-core configurations and OpenCL) found in the previous beta 1 and beta 2. See the screenshots below.
