Can you take a iPhone to an apple store that has a passcode to get reseted?

I found an iPhone 4 like a month ago but it has a passcode and I was wondering if I could take it to the apple store to get reseted please help

Just plug it in your comp and update and restore it (or take the sims card out )

No, its not your iphone.
i'm sure it was reported lost or stolen and is blacklisted, making it useless as a phone
apple will return it to the owner.

Not sure about that. But here's a tip that will clear the Passcode. Put the iPhone in DFU mode and Restore to the latest iOS version.
