I am not a big fan of the camera in my iPhone. I wish that it had better low light performance, better optics, and a flash. I mean if Motorola can make a phone with a real point-and-shoot camera crammed inside, so can Apple. That said I have seen some decent pictures taken with an iPhone.
If you like to shoot images with your iPhone a new tripod kit is available called Blur. The Blur system is three pieces. A tripod adapter has a threaded port on the bottom to connect to the tripod and securely hold the iPhone.
The system also includes a small tablet top tripod. The final component is Blur software that you have to buy for 99 cents on the App Store. The software adds adjustable photo delay, the ability to shoot multiple pics with delay, and a level feature within in the app. The Blur hardware sells for $14.99.
