Joby GripTight
The world is not lacking for iPhone gadgets. However, this one is different. First off, it's phone and case agnostic. The strong, spring-loaded grippy part will fit every smartphone/case on the market. Second, it folds down small enough to go on your key ring or carry unobtrusively in your pocket. Great for taking group portraits or movie-watching on an airplane. Swiveling mini tri-base base is removable and has standard 1/4-20 thread so you can even fit it to a full-size tripod. $30 at Crutchfield.
