I bought a iPad 2 today hoping to get the new 2,4 revision. I bought it at Best Buy and they were unaware of this new update so the guy called their Apple rep and said they should have them. I bought a black 16GB (even though the back is grey not black...) and it is a 2,1. Am going to return it tomorrow, should I try a white? Is there any patterns showing up like only whites are 2,4 (like is shown on Andantech) or is it both colors and just a real crap shoot in getting one?
