Apple has disabled a jailbreak detection API, but no one knows why. Apple did this without any explanation. This jailbreak detection API could see if your iDevice is modified or not, and disables the feature to sync with iTunes. This can mean two thinks. One, Apple finally surrendered and let jailbreakers do his thing “but that’s very unlikely”, or Apple found an other way to stop people from jailbreaking their iDevice. We don’t have more information yet but will let you know when we do.
