Okay folks, this is for you diehard Vox users who love the tablet as a reader and don't want to spend $100 or more to upgrade to a newer one because there are very few apps that support Gingerbread anymore. I contacted Dropbox support and they were unhelpful. But I finally found the old app here and it installed and works great.
