Security

The purpose of iPhone restrictions is to lock certain functions of the device. They are also referred to as Parental Controls, capable of hiding songs with explicit lyrics, preventing YouTube from running, etc.

Without the four-digit passcode restrictions can't be changed. If you have forgotten your restrictions passcode you must restore your iPhone using iTunes to reset the passcode. When asked, do not restore the iPhone from backup, otherwise the old passcode you don't know will be enabled.

You can't.

The entire purpose of the lock code is to keep the iPhone from being accessed by someone who doesn't know the code. Unfortunately, that's you.

In order to start using your iPhone again, you'll need to restore the phone via iTunes. You'll lose any data that's new on your iPhone since your most recent sync.

To protect your information in the event your iPhone falls into the wrong hands, set a passcode. If set properly, the iPhone passcode must be entered before the iPhone can be used.

1. Touch Settings -> Passcode -> Turn Passcode On
2. Enter a four-digit passcode
3. Re-enter the passcode for verification
4. Choose a time interval under Require Passcode
5. Select ON or OFF for the Voice Dial and Erase Data options

The shorter the Require Passcode time interval, the more secure your iPhone will be. Longer times mean longer spans during which unauthorized access can occur.
