Palm Pre users can now grab the Google Voice client called dkGoogleVoice for their beloved device. It’s an unofficial app — i.e. not made by Google — but it should do the job just fine. From the UI, you can choose contacts from your address book or dial a number, and call or text them using your Google Voice number. Be aware that it’s still under development and comes with quite a few bugs. Still, if you need it, there’s no reason why not to try it out. Moreover, if you find is useful, you can donate and help developers make it even better. 😉
