[Beta News] iPhone SDK and iPhone OS 4 beta 4 are now available from the iPhone Dev Center

iPhone SDK and iPhone OS 4 beta 4 are now available from the iPhone Dev Center. Posted May 18, 2010, this is build number 8A274b and introduces 11 new frameworks

• Accelerate
• AssetsLibrary
• CoreMedia
• CoreMotion
• CoreTelephony
• CoreVideo
• EventKit
• EventKitUI
• iAd
• ImageIO
• QuickLook

Some known issues remain, for example:

• iTunes 9.1 does not support folders. Syncing with iTunes 9.1 may erase any folders created on your device.
• Your device will not appear in Find My iPhone at me.com
• Starting in Beta 3, the AVAssetReader and AVAssetWriter classes have been removed from the AVFoundation framework.

But many issues have been fixed, most notably:

• FIXED: The camera (photo/video) and screen shots functionality is broken.
• FIXED: Starting location services using the startMonitoringSignificantLocationChanges method does not result in the delivery of location updates under some circumstances.
• FIXED: The time limit for task completion has changed from 5 minutes to 10 minutes.

  

This is by no means an exhaustive list of Beta 4 changes, for that please see the iPhone SDK Release Notes for OS 4.0 Beta 4.
