I've seen someone ask this before iOS 5 was released, but was it ever confirmed that iOS 5 now definitely does come preinstalled with a newly purchased ipad2?
Im sure there are places that have older stock with its iOS 4 still on them, Walmart or target maybe. Definitely if you get one at the apple store it will be ios 5. But there is no way to know until you open the box and turn it on.
Why do you still want iOS 4 anyway? I can't think of a single reason.....
Jailbreaking perhaps?
Bought yesterday at Best Buy, came without iOS5 installed.
