Well the iPhone is actually a pretty decent camera, but it is hard to hold and hard to see. Folks have been working on this though, so here are some things to buy:

• Camera+ is a totally cheap ($3) iPhone app that gives you more control. You can even see your iso and shutter speed and it has a stabilizer mode • Jag35 iPhone Shooter makes a huge holder so that you can hodl the thing without dropping it.$50 gives you a frame so you can put it on your tripod or throw a Marking plate on it or a handle (\$20)
