iOS 7 Beta 4 is coming out today, that much is certain given that Apple has already made the download links available.
And while the appropriate links are posted online, Apple’s servers won’t respond with an IPSW when you click them. The company has yet to make the seed official.
iOS 7 Beta 4 for iPhone 5 carries the build number 11a4435d, according to the MacRumors forums.
Over at BGR, several sources are quoted as saying that Apple is planning to roll out iOS 7 Beta 4 later today. In all fairness, the presumably delayed software seems to be just around the corner.
The report also mentions that Apple plans to release another two betas before finalizing the software. The sources added that iOS 7 Beta 4 is likely to deliver bug fixes, some user interface / graphics enhancements, “and a couple of other updates.”
