You will need to do a factory reset on the iphone in order to clear the passcode. When setting it back up you will need to login with the username and password ***** the Apple account that the phone is registered to.
Before we begin, please ensure that you can login to your Apple account.
If you don't know your password, please click on "forgot password" and follow the instructions on the screen to reset the password. Let me know when you've sucessfully accessed your apple account and I will walk you through resetting it to factory.
