There is a new version of GMail Mobile for your phones. If you have a Java Virtual Machine or Java emulator on your Windows Mobile phone, you can download the latest version at http://gmail.com/app.

The new version boasts less data consumption, faster performance, a new contacts viewer to browse your GMail address list, outgoing mail footer to let notify recipients that the email was sent from a mobile device, click-to-call phone numbers, and email draft-saving. Thanks to Mobility Site for the info.
