It's no secret that Apple's been keen to monitor the lot of naughty jailbreakers, but it turns out the company has recently shelved iOS 4.0's jailbreak detection API with no explanation given. While this has little effect on the average user, Network World explains that this is bad news for enterprise IT and MDM (mobile device management) vendors, who will now have one fewer channel for checking whether a user's iOS device has been jailbroken and thus become vulnerable to attacks. That said, apparently this isn't a huge loss for the MDM vendors, anyway; but the real question is why drop the API now? Could its presence alone be a threat? We'll probably never know.

Apple has just completely removed Jailbreak Detection API for iOS! It has been completely disabled or removed from iOS 4.2.1, as NetworkWorld reports. This is very shocking from Apple.
