If you're using [UIImage imageNamed:@"name_of_image"] (without the file name extension) to load in an image from your app's bundle, it will fail in iOS versions earlier than 4.0.

Today, I got an email from Eddie Babcock from the Y! Geo team informing me that this was due to a regression and that they will be issuing a fix today that will revert the API to its original state.
