i just recieved a refurb 16gb 3g ipad 1 i bought from cowboom.
when i turned it on the 3g was already activated and working.
i didn't sign up for anything and when i select view account under cellular data it asks me for a username and password because the fields are blank...
did i just get lucky? is the sim that came with it attached to someone else's account and probably just be turned off in a month when they recieve the bill?
