Developers have yet to uncover changes
Apple is now seeding a fourth beta of iOS 6 to developers, accounts say. The firmware's build number is 10A5376e, but beyond this few other details are available. As with past iOS betas, it will likely take developers a few days to discover all the features added since the last release.
The final version of iOS 6 is due sometime in the fall, likely around the same time Apple announces a sixth-generation iPhone. The upgrade will make a number of important additions to the OS, such as an overhauled, Google-less Maps app with 3D graphics and turn-by-turn navigation. Some other examples include native Facebook integration, and the introduction of Siri to the iPad for the first time.
