If you hae an iPhone 4 I thoroughly recommend a Glif http://www.theglif.com/
The Glif is a tiny (fits in pocket) tripod adapter and stand – I was using it tonight to angle the iPhone so I could watch some TED video while barbecuing  our steaks. (I know it’s after Labor Day but I still like a nicely done steak.)
The Glif is an amazing piece of design, and the injection mold for mass production was crowd-funded via Kickstarter.com.
