How to unlock an iPhone 4s with ios 8?

I found an iphone and no one ever came to claim it so I got to keep it. It had just been updated to ios8 so no one was able to use it to call. I tried to reset it but I keep getting stuck at a part where it asks for the Apple ID. The previous owner's id is still in their so it won't allow me to continue.

Do I have to jailbreak it? And if I do how?

Policies regarding employing own children?

From what understand my father is a manager of the IT department of a smallish business. It came up in conversation if he'd be able to employ me into the company, but he wasn't sure if it would be against some sort of company policy.

I was wondering what the policies are in relation to employing your own children. To reliterate, he is not the man in charge of the entire company - just the IT department. Would I need an interview like everybody else? Would he be able to take me on as a sort of apprentice? Help would be appreciated.

Apologies if this is horribly written and/or is full of spelling errors. I'm writing this on my iPhone.
