After Apple's developer site has gone back online after a security breach, iOS 7 beta 5 download is expected to be released on August 12.

So far, Apple has already released 4 beta versions for the iOS 7, with the latest made available on July 29. Experts are now predicting that the succeeding test version which is the iOS 7 beta download will be available on August 12.

According to iPhoneHacks as cited by Know Your Mobile, Apple will go back to its usual two-week release cycle for the iOS beta versions. This means then that the iOS 7 beta 5 download will already be announced on August 5.
Furthermore, according to the post,  reader from iPhone Hacks shared an interesting pattern about the release of iOS 7 beta downloads. According to the comment, each new iOS 7 beta release was typically launched before the expiration of the previous test version. Check out the release schedule of the iOS 7 beta firmwares below:

iOS 7 Beta 1:

Release: 10 June 2013

Expiry date: 24 July 2013

iOS 7 Beta 2:

Release: 24 June 2013

Expiry date: 8 August 2013

iOS 7 Beta 3:

Release: 8 July 2013

Expiry date: 29 August 2013

iOS 7 Beta 4:

Release: 29 July 2013

Expiry date: 12 Sept 2013

Since iOS 7 beta 4 download will expire on September 12, it may be predicted that iOS 7 beta 5 'download will arrive to Apple's developer site on August 12.

Because of this pattern, it also suggested that the release of the iOS 7 beta 4 download was actually not delayed by the Dev Center security threat as everybody had thought, since according to the pattern, Apple is still following its schedule.

Furthermore, as the final iOS 7 nears its launch, reports are now saying that the ioS 7 beta 6 will be available two weeks later, in August 26, and then the final Gold Master beta for the latest Apple mobile software will launch on September 9.
