MacRumors Forum poster aibnr noticed earlier today that the iOS 7 Beta 4 download appeared to be posted on Apple's developer servers early this morning, ahead of an expected release today. If released today, Beta 4, with a rumored build number of 11a4435d, would come three weeks after Beta 3 was released at the beginning of July. Clicking the purported download link, available here, returns a 'Your session has expired' error page. Other URLs with similar build numbers, on the other hand, return an 'Access Denied' error message. Apple is expected to release Beta 4 later today. BGR has some additional iOS 7 beta-related claims as well: 9to5Mac somewhat corroborates this, claiming that Apple is nearing "zero-priority-1 bug status", meaning there are no critical bugs left in the OS and the company is getting close to releasing a "GM1" candidate internally. Apple typically releases several internal GM candidates before releasing a final GM seed to developers for testing. Article Link: Apple to Release iOS 7 Beta 4 Today, Two More Betas Coming?
