Yes, the curve made me wonder whether I was seating it right, but I tried a few times and then last night asked my husband to try, but it didn't play. We also tried iPhone 4S and 4, both on iOS 5, and they worked fine. My touch 4 also works fine on two other docks (Sonys) since I upgraded.
I'm not sweating the Bose, though, because my husband just uses it with an auxilliary cable with his iPad when he cooks.
