"New" iPad Air has serial number from 24 November 2013 in Notes App...

Is this supposed to be there?

I bought it brand new from Tmobile just over a week ago. How/why is this here? Is this evidence of Tmobile trying to repackage a refurbished iPad Air as New? I'm about to lose my shit over here... Thanks, Breon
