After facing an 8-day downtime in its Developer Website due to what they said was a security intrusion, Apple gets back on track today by releasing beta 4 of iOS 7 for the iPhone , iPad and iPod Touch. iOS 7 betas are released to developers for testing purposes, these do not have an specific release date, but since iOS 6 these have been release in a two week cycle; this has also been the case for iOS 7 beta, but was interrupted by the downtime.
It is too soon to say what's new with iOS 7 beta 4, but it is expected that Apple continues to squash bugs, specially UI bugs, and continues to refine the experience.
Apple is expected to release iOS 7 to the public some time in September or October.
More on this later on.
