Black Hat has posted a video of Ivan Krstic, Apple's Head of Security Engineering and Architecture, giving a talk at the 2016 Black Hat USA Security Conference. The presentation was called Behind the Scenes with iOS Security.

Description:
With over a billion active devices and in-depth security protections spanning every layer from silicon to software, Apple works to advance the state of the art in mobile security with every release of iOS. We will discuss three iOS security mechanisms in unprecedented technical detail, offering the first public discussion of one of them new to iOS 10.

HomeKit, Auto Unlock and iCloud Keychain are three Apple technologies that handle exceptionally sensitive user data – controlling devices (including locks) in the user's home, the ability to unlock a user's Mac from an Apple Watch, and the user's passwords and credit card information, respectively. We will discuss the cryptographic design and implementation of our novel secure synchronization fabric which moves confidential data between devices without exposing it to Apple, while affording the user the ability to recover data in case of device loss.

Data Protection is the cryptographic system protecting user data on all iOS devices. We will discuss the Secure Enclave Processor present in iPhone 5S and later devices and explain how it enabled a new approach to Data Protection key derivation and brute force rate limiting within a small TCB, making no intermediate or derived keys available to the normal Application Processor.

Traditional browser-based vulnerabilities are becoming harder to exploit due to increasingly sophisticated mitigation techniques. We will discuss a unique JIT hardening mechanism in iOS 10 that makes the iOS Safari JIT a more difficult target.

Notably, Krstic announced an Apple Security Bounty program during his talk. The bounty will pay hackers up to $200,000 for finding flaws in Apple's software.

Irony: several people in that crowd recording on jailbroken iphones

Except they did that to their phones. Security alone is what the focus is here minus jailbreaking. In fact, prove it that these are jailbroken.
