I've read that the paid version of Docs to Go is quite versatile, but I still don't understand what the free version that comes with my BlackBerry can be used for. I don't have Microsoft Office, Excel, or Word. I only have Wordpad and Notepad. I tried emailing a couple of Wordpad and pdf documents to my BlackBerry, and I also tried transferring them with DM. I couldn't get Docs to Go to do anything with them or even to access them. Do I need Office, Word, or Excel to use Docs to Go? For what can I use my free version of Docs to Go?
