I've not seen anything in the SDK that would lead to a problem in their apps, unless they used a private API and Apple rejected their app because of it. Everything that's in the 2.2 to 3.2 SDK's work on iOS 4 (gotta love that backwards compatibility), just not as well as straight iOS 4 code. Maybe something with the new multitasking feature might be causing an issue, but all they have to do is add one key to a configuration file and the app works the same as on older OS's.

Curious. I'd love to know what's going on, but I doubt they'll tell us!
