Apple Disables Jailbreak Detection API in iOS 4.2.1

Six months after introducing a jailbreak detection API in iOS, it has been dropped out of the next iOS. No explanation what so ever has been yet provided by Apple. Device management vendors say the reasons for the decision are a mystery, but insist they can use alternatives to discover if an iPhone, iPod touch or iPad has been modified so they can load and modify applications outside of Apple's iTunes-based App Store. how to get your ex back

This detection API let the MDM applications in effect ask the operating system if it had been compromised. Jailbreak exploits typically change a number of operating system files, and exploit one or another low-level OS features to let users directly load their own or third-party applications.

Prior to iOS 4.0, some third-party developers implemented their own methods to detect whether the operating system was compromised or not. But this new detection API in iOS 4.0 allowed easier and simpler way to query the OS about the jailbreak, thereby triggering automatic responses such as alerting the helpdesk or shutting down access to corporate ExchangeServer e-mail.
