Actually, it's quite common that Apple mobile products are slightly bent. I handle quite a lot of portables at work, and I've learned from a guy I know at an AASP how to fix it: you just bend it the other way.
That is, or at least has been, the official way to fix these things. Take the unit out back, bend it the other way, check for flatness, repeat until flat. Return to customer.
It's metal, of course you can bend it slightly. I would assume, that if these bent iPads are for real, they can just bring them to an Apple Store and the "genius" will take it out back, bend it right, and then return it.
I would not recommend to bend it yourself though, let the genius bend it, if it breaks, you get a new one.
