Suction cups are so very useful and were once commonly used on just about everything. iLoveHandle's Barnacle is a multi-purpose dual suction cup stand mount that sticks to the flat surface of gadgets like the iPhone 4 and iPhone 4S allowing for car windshield mounting, desk mounting and other sorts of flat and slick surfaces you can think of. And it's quite a sucker too, capable of securely sticking to your phone even on a bumpy car ride. The Barnacle stand mount comes in many colors for $4.95. One of the more affordable mountable stand solution you can find.
Thanks for the tip, Rich!
