Apple iPhone app developers can now access an updated version of iOS 4.3, which includes a new beta version of the software development kit (SDK).
Registered developers can now download iOS 4.3 from Apple's Developer Connection Site.
Apple has not revealed much information on how the update is an improvement of the last beta release, other than some notes on error reporting. There are no new announcements on any major features.
Earlier beta releases included third-party streaming options for AirPlay, full screen iAd banners, and an option for developers to get statistics from HTTP live streaming from within their apps.
