iPhone SDK 4 beta 3 and iPhone OS 4 beta 3 are released.

Details are scarce due to Apple Developers NDA. According to sources iPhone SDK 4 beta 3 and iPhone OS 4 beta 3 are released.

Notes from the imaginary sources:

  • So far beta 3 is using less memory than beta 1 & 2.
  • Lots of bug fixes.

As usual, please do not install any beta releases unless you understand the risk. Beta softwares are generally buggy.

Since the knuckleheads at 9 to 5 Mac already revealed some of the features from iPhone OS 4 beta 4:

Portrait Orientation Lock and iTunes Control

More info if they’re made available.
