I have to admit that it was more then likely user error on my part. The warehouse didn't show a later version number, so i was still on 1.2.9.
Last night something or another made the "search for updates" feature seam apparently broken, so i went through all the appz manually and enabled the repo's, if they were possible to enable. And this morning there was a bunch of completed updates, and re-registering works. My phone has been exploding the latest few hours, so sometimes i guess you really should be careful with what you wish for ;- )
