It appears that Apple has started seeding iOS 6 beta 4 (build 10A5376e) to developers as an over-the-air update. Beta 3 was released about 3 weeks ago in the Dev Center. iOS 6 will power the next iPhone, rumored 7-inch iPad, and iPod touch when it is released to the public this fall.
Update: Beta 4 is now available in the Dev Center. A developer update has also been released for Xcode and the Apple TV:
Update 2: It doesn’t look like there’s much to this beta besides the usual bug fixes. There are some big fixes for the Apple TV, including an issue where the software would show the wrong resolution and some issues with the system restarting randomly.
Today’s iOS 6 Developer BETA 4 (10A5376e) expiry date is unchanged from BETA 3. It expires on September 30, 2012 @ 8PM [EST]

If Apple’s next media event is indeed happening on September 12th, we expect to see maybe one or two more iOS 6 betas before the final GM release.
