My company has 10 iPad 2s that we've been using since August. One of the apps we like is Print to PDF. When we upgraded to iOS 5 recently, that app went away. (Actually, all the apps went away but we were able to download the others again from the App store.) I did some research and found a notice on the Print to PDF website that the app is no longer available in the App store, but that you can continue to use it if you already have it. (I'm not allowed to post the link, but it's just Print to PDF dot com.) Since it isn't in the App store, does anyone know of a way to get it back? We did pay for it, but it's not listed with our purchased apps. We've only had time to upgrade about half of our 10 iPads, so some of them are still running the old iOS and still show Print to PDF as one of their apps. Is there a way to save it before upgrading the last few iPads, and then put it back on all the iPads?
