Apple should stock up on Kensington's new BungeeAir iPhone alarms. This case doesn't protect your iPhone from falls, but warns you via a wireless security tether when you get a certain distance away from your phone. The distance can be decreased or increased to your liking with the BungeeAir app. This is the perfect invention for people who love to leave iPhone prototypes in California bars!
The 3-in-1 accessory for the iPhone is a wireless tether, battery and case. You just put your iPhone inside the case, attach the tether to your keys or pants, and you will never lose your iPhone ever again... Or at least that's the theory. If you still manage to forget your phone, the case automatically invokes the iPhone's passcode security. You can then locate it by using the "find" button which sounds another alarm on the device.
