The QuadLock iPhone can be used to lock your phone into place on your bicycle, car dash, or pretty much anywhere else you can think of. The case itself is made from tough polycarbonate plastic, and can be mounted in both portrait and landscape mode depending on your personal needs.
The mount itself can be affixed using the included sticky-back adhesive onto any flat surface. For more adventurous locations, you can also attach the mount using a fixing screw to ensure it won't fall off during your exploits.
Currently the only way to pick up the case is to donate to the QuadLock iPhone case project on Kickstarter. The project recently met its goal, which means it is fully funded. Since the project is still technically in the funding stage, cases are discounted from what they might be when they eventually hit stores.
Those who pledge US$25 to the project walk away with a QuadLock system, $50 gets you a system designed specially to be used on a bike, and $80 gets you a Kickstarter Limited Edition version of the case.
