I did try "Import contacts" to import a vcf from my google address book and now I have all my contact from google in the edge's contact application. So if this doesn't work for you let us know what is the problem.

I'm not sure what is the issue with the lack of syncing with google apps. In theory Android is supposed to be able to sync gmail, calendar, and contacts. Let's hope the Froyo update will solve some of this issues as well...
