Owners of Nokia's 770 Internet tablet are probably feeling a little more chatty today than usual. The company unveiled a software upgrade for the handheld that includes an onscreen QWERTY keyboard and Google Talk software for instant messaging. Going against rumors that such features would be included on an entirely new gadget, Nokia instead is offering the upgrade to current owners for free. The 770 is a portable device that can wirelessly connect to the Internet, accessing e-mail and Web pages on the go. The addition of Google Talk doesn't just bestow the user with IM abilities — it also enables making phone calls via VoIP (Voice over Internet Protocol), which is an additional feature of the software. Of course, if you really want to talk on the phone, I'm sure Nokia could recommend some other products in its lineup.
