As far as I can tell, the only feature of iOS 4 that Apple has officially said won't work with certain older iPhones is multitasking for the 3G.
Aside from the obvious features that require new hardware (FaceTime, gyro related stuff), anyone else know what other features won't work on older iPhones?
(But at the same time, I wouldn't want anyone to break NDA's unnecessarily.
