Water-logged iPhone 7 Plus?

Hi! So I was snorkeling in a lake and found a rather new iPhone 7 Plus about 7 feet down. I have been drying it and the SiM card out for about 2 hours and plugged it in. The phone is still working, but as the phone is not mine, I don't know the password to fix it on Itunes. Any suggestions?

Put it in rice

Turn it in to the police. You think someone is going to help you steal an iPhone.

Options:
1) Turn the phone in to the nearest cell phone service provider store.
2) Turn the phone in to the nearest Law Enforcement offices.
2) Electronics recycle.

Without the password, you have a brick.

Do the right thing. Turn it in to the closest iPhone shop, or the police. Tel then how you found it - great story - and you will feel better for being honest about it.

Take it to the police.
