CleanUp is a terrific, free utility for iOS that has only one job -- it quickly deletes photos cluttering up your iDevice. You might wonder why you'd need such a thing. The answer is that Apple's method is a bit cumbersome. You can get a thumbnail view of your photos, and check off the ones you want to trash, but you don't see the photos full screen, so you might inadvertently delete pics you wanted to keep. Apple also provides an option to delete them from a larger view, but when you click on the trash icon you get a popup asking if you are sure you want to delete.
