Many camera apps for iPhone feature self timer. But if you want to more directly control your photography, the Belkin shutter remote would be more suitable for you.
This is an innovative shutter remote that measures 3.5 x 1 x 1/2 inches, and designed for both iPhone 4 and iPhone 4S. As we can see from the images, the iPhone camera remote consists of two parts including a stand and a remote control, so you can easily use the stand to prop your iPhone for group photos or self-portraits, long exposures or stop-motion. With the help of Bluetooth wireless technology, you can take photos with your iPhone 4 or 4S from up to 30 feet away. Apart from that, the compact design allows you to carry the iPhone camera remote with ease.
