Apple seems to be sticking to the company’s two-week cycle for iOS 7 beta releases, a sign that it is making good progress ahead of the software’s public release this fall. BGR has been informed by trusted sources that iOS 7 beta 3 is currently scheduled to be made available to carriers for testing on July 8th. These are the same sources who accurately foretold the release timing of Apple’s last iOS 7 beta, and just like iOS 7 beta 2, it is likely that the new software will be released to developers on the same day it reaches carriers. Apple finally began supporting the iPad in iOS 7 beta 2, so we should see beta 3 made available for all iOS devices at the same time, including compatible iPhone, iPad, iPod touch and even Apple TV models. We are told Apple is still working on refining iOS 7’s design in order to make it cohesive across the entire OS, and we should see further refinements in beta 3.
