TriggerTrap has just unveiled a new app ($10, App Store) and $10 cable that connects to one of over 270 digital cameras and allows remote control and full control over the camera. This can be especially useful for DSLRs, where it allows full-fledged access to all standard and more features, eliminating the factory remotes. Any iPhone, iPad, and iPod touch running on iOS 5 can be used with the app.
