GPS as a technology has been around for quite some time already. The fact remains, however, that it still is a much desired piece of technology. From mobile phones to PDAs, the idea of having a GPS receiver on these gadgets is enough to excite the gadget enthusiast. So what have we here?

Freedom Input has released a mini Bluetooth GPS receiver that promises to transform any smartphone (that is Bluetooth enabled) to a fully functional GPS navigation system. When we say mini, we mean mini. Take a look at that picture and you will realise just how small this baby is.

Weighing in at 30 grams (1.06 ounces) and measuring in at 39 x 33 x 20 mm (1.54 x 1.30 x 0.79 in), Freedom Input’s Bluetooth GPS receiver is small and light enough to hang on your keychain! Though small, this gadget can connect to 20 satellite channels simultaneously and can work for you for 10 hours straight (single charge). Thanks to Bluetooth technology, it will work within 10 meters of your Bluetooth-enabled device. When you buy the kit, you get the following with it: Freedom Mini GPS, 12/24v Car charger cable, USB Home charger cable, Key link, Quick Start Guide and hints manual.

So what is the catch? Aside from the fact that this thing is so small that you may lose it as easily as you lose your keys (no pun intended), it is a good deal. By the way, it comes with a $99.99 price tag.
