Re: iphone passcode
None of us here knows the passcode to your iPhone, and I *assume* you're referring to the lock screen passcode. If so, you will have to connect the iPhone to your computer and then restore it via iTunes, however, if iTunes asks for the passcode you will not be able to restore it. Of course, you can put the device in recovery or DFU mode to get iTunes to restore it, but you will lose EVERYTHING that is currently on the device. If you're referring to the iCloud passcode that unlocks the iCloud activation lock, there's nothing anyone can do for you except direct you to the iCloud website where you can use Apple forgotten passcode option to try and retrieve your passcode.
