Docstogo Documents To Go - Use Word, Excel, PowerPoint and Other Files on your Smartphone or PDA works great on the PDN! This app is pretty good on my Hero, the only short side is the smaller screen. With the PDN's 7 inch screen its amazing!If you've bought the full license for DocstoGo and are using a 1.6 Android ID you probably won't be able to see it on the market, I wasn't able to.You have to pull 2 files from your actual android phone to get this to work. Download both the zip file (the license with the xml file in it) and the actual apk.1. Push the zip file to /data/app on the PDN2. install the apk to the PDN (/data/app)it should work (it works on mine!)Ok, modified instructions using the modded 08 firmware:Install the app on your android phone - pull com.dataviz.docstogoapp.apk from /data/app-private/ on your phonepull com.dataviz.docstogoapp from /data/app on your phonePush com.dataviz.docstogoapp.apk to the PDN's /data/app-private/push com.dataviz.docstogoapp to the PDN's /data/appreboot the PDN.Start the "Documents To Go full Version Key" app on your PDN - it will have a download now button, click it and it'll bring you to a dataviz webpage with a link to download the main app. do so...once installed you should have the full unlocked version of DocsToGo.Please pay for the app, its well worth it.
