After about 40 days of beta testing, Apple released iOS 4.4 on Monday, July 9, exactly one week after the release of the final beta.
Hidden in the iOS 11.4.1 update is the new USB Restricted Mode that Apple has introduced in the iOS 12 Beta and makes brute-force tools like GrayKey and Cellebrite completely useless. While the limited USB mode was released in iOS 11.4, it would take seven days for the iPhone to unlock to lock all USB accessories. This newer version limits this to just one hour.
This shorter period of time makes your iPhone more secure, but also requires you to unlock your iPhone with a password, Touch ID, or Face ID when you connect it to iTunes for loading or syncing with your computer, but only when it's not unlocked within the last hour.
