I recently upgraded to a 16G SD card in my N1. I backed up the entire contents of my old 4g card and put them on the new card. Ever since, I have not been able to update any apps that have ever resided on my SD card, even if they are now located on the phone. In an effort to resolve this, I uninstalled the afflicted apps, and now I cannot even download them again! I simply get "installation unsuccessful." Anyone have a fix for this? Got a long road trip coming up and I'd really like the use of some of these apps!
