How to figure out passcode on Iphone 5?

I found an iPhone 5in in my front yard. Went and bought a charger for it and it needs a passcode. It says no service on the which means they got it turned off I guess. Is there anyway to bypass the passcode or figure it out?

You have to run recovery mode. Passcodes are put on for a reason: they are IMPOSSIBLE to bypass unless you erase everything on the phone. And you will need cellular service as well.

Recovery mode: http://support.apple.com/.../kb/HT1808

All you need is a lightning cord to unlock it
And itunes… Just hold home button then put in the cable and it will ask you to restore on itunes

Youll have a blank iphone like new
