An easy way to unlock iPhone If you have set up synchronization with your computer through iTunes, you can unlock the iPhone by resetting the counter of incorrect attempts to enter. Of course, the method is suitable if the password is not forgotten, but until the next input attempt, the screen displays not minutes, but hours and days. 1. 1. Connect the device to your PC via cable. Open iTunes and find the "Devices" item. In the new window, click the "Synchronize" button. 3. Once the iPhone is synchronized with the computer, the password lock will be disabled and you can enter the code. But note that if the smartphone has not previously synchronized with the PC, the scheme will not work.
