We reported earlier today that Apple was expected to seed iOS 7 beta 4 today. The release was actually expected last week, but given the fact that Apple Developer Center was down for almost eight days, iOS 7 beta 4 comes later than expected. Apart from a host of items listed in the changelog, the latest beta of iOS 7 brings a number of improvements and bug fixes.
Apple has reportedly made a couple of subtle tweaks to the lock screen. To the left of the “slide to unlock” text an arrow pointing right has been added. The graphics for quick launch and notification center are also said to have been changed to straight lines as opposed to arrows. Beta firmware is only available to registered Apple developers, who can either download it from the Developer Center or on their devices over-the-air if they have a previous beta of iOS 7 up and running. A recent rumor suggests that Apple may releases two more betas before finally rolling out the GM build. Apple has said that it will release iOS 7 for the public this fall, an exact date is yet to be provided.
