Proporta Freedom Keychain GPS

Just in case the cellphone that you pick up does not come with any sort of GPS functionality, fret not. There is the Freedom Keychain GPS from Proporta that is touted to be the most compact and neatest GPS receiver available in the world. It is powered by the vaunted SiRFStar III GPS chipset and handles up to 20 satellite channels at a time up to a stretch of 10 hours. The Freedom Keychain can be hooked up to phones or PDAs via Bluetooth and is compatible with all major mapping software found today. The Proporta Freedom Keychain GPS retails for $130, so make sure when you keep better track of the set of keys attached to it lest $130 disappears along with it.
