Had the same issues with a new Nexus. Would not download apps from either wifi or 3G. I cleared both the data and the cache on the download manager. Do this from settings and then sekect apps. Select ALL from the right hand dide of the screen and scroll down to the download manager. Turn off the phone completely after that and power on again. App downloads now wirk cortectly. Good luck
