I just got an ipad 3 64GB from craigslist. it is brand new. I went through the initial setup using my existing ipad profile saved in icloud previously. when I first used it, it popped up and asked for my apple Id password and my email passwords, as expected. but it also popped up and asked for password for an apple ID that is not mine. something like "firstname.lastname@example.org" is it possible the ipad was used before? but it was loaded with my profile from icloud.
