Kensington has a new iPhone 4 case out that adds a number of nice features to your iPhone without adding significant bulk.
The BungeeAir Protect Wireless Security Tether and BungeeAir Power Wireless Security Tether for iPhone help you remember your iPhone, secure your iPhone and can find your keys. The Power model adds a battery to the mix so that you don’t need to charge up as often.
The BungeeAir iPhone cases aren’t available to purchase yet, but you can pre order them from Kensington for $79.99 and $99.99. The Power case is more expensive.
These cases are different that most on the market in that you can use the companion app to replace a few as seen on TV gadgets and ensure that you don’t leave your iPhone behind.
The Remind function will cause your keyfob to buzz and vibrate when you get out of range, allowing you to quickly return and get your phone or hail down that cab again.
The Protect function locks your iPhone when you get out of range, allowing you to leave your phone on your desk without worrying that someone will use it to make prank phone calls to the boss or ring up app purchases with your account.
If you lose your keys, you can use the Kensington app to force the keyfob to vibrate and buzz, so that you can figure out where you left them. This is a nice way to get rid of at least one as-seen-on-tv gadget in your house.
Does this app and case combo appeal to you? When you consider the extra 4 hours of power found in the Power version, it seems like a much better deal for only $20.
