Supporting multiple iOS versions is a real pain!
The last update for Hyper WARP (iPhone v2.7) has a problem only on iOS 3.x - ARG!! I tested the update several times but failed to test the final build (<- yup I know, what a dummy!). Even after I posted THIS PAGE on our site... double ARG!
Makes me reconsider supporting pre-iOS 4 at all... When we started both iOS 2.x and iOS 3.x were available but almost all of our apps only supported iOS 3.x. Man that kept things very nice for testing, no need for a 2.x test device. Now with a bunch of devices still running iOS 3.x, I've really got to give this some thought.
