Google already had a version of Google Voice available through mobile Web browsers.
But Google described the new version of Google Voice as a "Web app," noting that it is much more interactive than the previous browser-based version of the service, with the ability to listen to voice mails directly from within the browser and to dial phone numbers on an interactive on-screen keypad.
Google said the new version of Google Voice is designed for iPhone 3.0 and higher and Palm Inc Web OS smartphones.
