If you wish you could tweet during that round-the-block 5K, then Motorola\'s latest update to MOTOACTV is for you. The fitness computer will display Facebook and Twitter messages on the device as well as offering more accurate mapping, easier WiFi network setup and more flexible workout planning. Additionally, golfists who plumped for the Golf edition get some more links-appropriate features like tee location options and putt distance-tracking. You can get the update by connecting the device to your computer and Motocast will handle the rest.
