iPhone OS 4.0 Beta 4 Reveals Support for Leaked Devices

Yesterday, developers received iPhone OS 4.0 Beta 4. In the code of the Software Development Kit (SDK), there are references to "AVCaptureFlashMode."

The code for flash control also appears for the new iPad 2nd Generation and iPod touch 4th Generation. Suggesting that when updates for both come out, they will have cameras accompanied by LED flash.

This coding is almost definitive proof that the prototypes that were somehow leaked of the new iPhone and iPod touch 4th Generation are legitimate.
The new iPhone 4th Generation is expected to be revealed by Apple at WWDC 2010 on June 7.
