This is a must have tool for those who love taking pictures on their iPhone. It is basically an aluminum wand that features a mount capable of holding any generation of iPhone (though only the iPhone 4, 4S and iPhone 5 are capable of taking decent pictures). This accessory is called the iStabilizer Monopod and it can be used with the iPhone still in the case.
The Monopod provides the same benefits as a tripod and is more portable and compact for carrying around. The mount is adjustable and can be used at any angle. It costs 35 dollars. [link]
