I quick check on DataViz's website indicates that you need BES 4.1.5 or higher for native attachment downloading and uploading. That's a bummer for me because my company's BES is something less than 4.1.5.
I just checked this out. I cant seem to find this Docs to Go app. But I do have OS 4.5 on t-mobile. I can save the files and open them in emails. I can create an email and find the file, then attach it. But I can't seem to find the file and delete from my memory card using my blackberry. Do I have to hook it up to a computer in order to delete it?
After I upgraded to t-mo's OS 4.5, I had to go back to Desktop Manager --> Application Loader and enable Docs to Go. The application was there, but the checkbox needed to be enabled.
