The latest - complete reset/ erase; setup as new iPad; installed apps; first app used SiriusXM, played, quit unexpectedly, went from app initalizing to home screen, then started again; later system froze on home screen, had to sys reset to start; later froze again, stuck on silver apple, sys reset.
Back to the Genius bar, will ask for an exchange and even push my luck a bit and ask for a black model to replace my white one.
Edited to add-- Genius Bar offered a replacement but refused to replace with a black model. Like for like is the policy. Which generally makes sense but I was a little put off by it given this product hasn't been on the market a week and I went out of my way to buy it on day one. So it goes. Ended up returning the iPad 2 to the military PX where I purchased it and may purchase another. Definitely won't go out of my way to do so as this has been a lot of effort for little reward. I do appreciate all on this forum and particularly those that offered advice.
