Can Apple unlock my iphone 5s ios 8?

My sister recently received a new iphone 5s from her friend, but the thing is it's Sprint and her friend had the phone linked to her old apple account so she has no idea what the password is. If I take it to apple would they be willing to unlock it for me?

Yeah, just tell the apple service agents what your problems are and they should be able to fix them because its their job to fix those problems.

Nope, you're completely locked out without the password.

No they won't unlock it for you as it could easily be a stolen phone.

Just ask your sister's friend to tell the password or remove the account and use your sister's account to set up the phone again. If you take it to the Apple store, they won't help you with it as you're not the original owner of the phone. They won't even unlock the phone for the same reason. Just have it sorted with your sister's friend. If you need help with unlocking the phone, mail me.
