How to get past iPhone 4 with iOS 7.1.2 lockscreen without Siri?

There's gotta be some program or something that allows you to get past the lockscreen/passcode on a iPhone 4 with iOS 7.1.2. Do you guys know what it is? If so, can you go through the steps very carefully? I promise to give 10 points for the best answer.

You can't. Apple takes security quite seriously, and makes it difficult to bypass the lockscreen (its there for a reason).

You could put the iPhone in DFU mode and download iOS 7.1.2 and restore the phone. However, if the phone had iCloud Find My iPhone enabled, you'll need to enter your Apple ID and password in order to get access to the phone. Remember, restoring your phone will wipe out everything.

I have a feeling this isn't your phone, but hey, what does it matter to me?

LOL. Just return the iphone to the real owner.
