How to secure your iPhone 4 and iPhone 4S

My iPhone is always with me, and I will admit to having mild panic attacks if I misplace it around the office or house. Only once have I had cause to go into major panic mode though, and that was when I managed to leave my iPhone and my car keys in a shop. Luckily it was the last shop I had been in, and my good fortune held up as not only had I left them at the checkout counter but the checkout assistant was a very honest person. I would not like to experience those 15 minutes of pure 'life without an iPhone' hell any time again soon though. Which is where the BungeeAir from physical device security specialists Kensington enters the picture.
