In the last couple of weeks I was able to invest a substantial amount of time into gwt-phonegap and mgwt. The work on gwt-phonegap is almost complete and it supports all of the phonegap api.
Also the documentation has had some major improvements, so that it will be much easier to get started with gwt-phonegap.
One major thing that happened was to change the package structure from de.kurka to com.googlecode.gwtphonegap to meet the requirements for artifacts to be uploaded the the central maven repository.
I will be releasing the first beta of gwt-phonegap 18.104.22.168 very soon and if all goes well, we are going to have an release in the central repo very soon.
In the next couple of weeks I will be focusing to get mgwt to 1.0 as well
