The iPhone camera is great, easy to use, and has the basics you need to take a photo. Although, you can't really say it not missing anything. The current camera app has Auto-focus, flash, and HDR but it could have more. With PictureMe you can add a timer and a rapid shot feature to your native camera app. This tweak adds and arrow to the bottom, that pops up a menu, and allows you to use some extra features. You can find PictureMe in the Cydia Store for $1.99.
