Apple’s reluctance to publish the official Google Voice app in its iPhone App Store hasn’t stopped Google from making its Voice app available to users of all kinds, as announced yesterday by the web giant.

Google revealed that it has already launched a web app compatible with both the Apple iPhone and Palm’s webOS (which powers both the popular Pre and Pixi smartphones), powered by HTML5 and allowing users of those handsets to make cheap calls through the Google Voice service.

The new app is freely available for download at the Google Voice site.
