I just received the iPad 3 I bought through an Amazon 3rd party. While I have no intentions of going through the iPad carousel of returns I'm as cursed as some of you seem to have been with very bad luck with faulty devices. I am curious enough to check the build date to see if I have an older or newer one, since I didn't get it right from Apple directly. How do I determine the build date? Is it on the box somewhere? Thanks in advance.
