Apple have been rigorous in ensuring that the latest installment of iOS will be delivered problem free by releasing a third version of the operating system to developers just a fortnight after they released the second.
The latest update aims to address issues with AirPlay, iCloud and iMessage. Cupertino have also reportedly been working on fixing issues with the new KeyChain feature as well as Find My iPhone and Bookmarks.
The new beta is also claimed to deal with issues widely reported by testers receiving two push notifications for a single event or in some cases receiving no notifications at all.
Despite extensive testing Apple are still set to release iOS 7 on September 18th.
