it was FEATURED in the film, but I doubt they actually ever had that thing flying on set like that, or even were able to use it in actual flying scenes. It's likely they were able to model it, but as you said, it's maiden flight was recent (December 2006), and thus is not in production. Maiden flight is first successful flight of a finished model. The F-22 had a maiden flight in the early 90s iirc, and wasn't introduced into the military until recently.
either way, F-35B is an AMAZING flying machine, and a very capable one at that.
