I found a iPhone at school, can I keep it?

So on Friday, I was going to my next class History and when I came in, I was the first student there and I sat down, and at the end of the table an iPhone with AirPods were on the floor under the desk so it looked like someone forgot them there so I went over and took them and put them in my backpack and I brought them home at the end of the day and I connected the phone to my computer to erase it since I couldn't guess the persons passcode, and I connected the AirPods to my phone so now I have two AirPod sets, and a new phone which is an iPhone XS Max compared to my phone now which is old

Added (1). I switched my SIM card into the new phone as well so i'm using it as my phone since I transferred my data to it

No, take it to the office

No, they are not yours to keep. You need to turn them into the schools lost and found for the owner to claim them.

No, if you lost your iPhone you would want to get it back.

Have you ALWAYS been a thief, or is this something new? You know you can't use this as a phone, since it's code and serial are not registered to you. If not already, the phone had been reported as stolen, and been bricked. And if their computer has "Find my phone" - well, do not be surprised if the Police come to your house. But the WORST is that you know you are lowlife thief. You can see that people here have no respect for you - bet you that some of them LOATHE you. Enjoy that stolen phone much now?

No, thats stealing

Turn it in at a police station or a phone store.

There's No reason, nor is there any excuse, to do otherwise.

Find out who owns the iPhone and give it back to them because what will happen is once the person finds out that has iPhone is lost he'll go online and report it stolen and the phone will lock up and they'll be absolutely no way for you to use it or to reset it.

TROLL!

Basically you are a screw-up. You found a phone, made no effort to return it to the owner, and then "fixed" it so you could make it yours. Too late to undo the bad now, Hope you get what you deserve, and soon.

THIEF!
