I finally found some time this weekend to update the gwt-phonegap project.
I made a new realease (Version 0.6) to fix some open issues and move to the latest version of PhoneGap (0.9.2) and GWT (2.1.0). (Changes)
As always, if you encounter any problems using gwt-phonegap feel free to contact me or use the issue tracker.
Note: If you are running on Android make sure to take a look at the getting started section, you will need to include a small Javascript into your html host page to make gwt-phonegap work.
If you are unaware what gwt-phonegap is feel free to read this blogpost.
