Nexus 1, although seen many phones have this same issue also 32gig micro sd. Updates just dont happen like they should on automatic updates. The update progress bar just sits there and notice comes up "update unsuccessful" looked everywhere but this seemed to work fine. 1. Unmount SD 2. Go back to each download (market download) 3. Cancel download 4. Then it takes you to app. push install 5. Download restarts and installs fine 6. Then go back and remount SD under phone settings 7. Then go to phone settings, applications, manage apps, 8. Pick the apps you just installed and move them to the sd card if possible. thats it works all the time now!
