Your BlackBerry may already have the free version of the Documents To Go viewer and editor loaded onto it. That's fine for casual users, but professionals who annex their smartphones into their virtual office will want the advanced creating and editing features of the premium version (compare features--PDF).
On BlackBerry phones, Documents To Go Premium Edition 2.0 adds four new features. There's a file browser to delete, rename, and copy and paste all the Microsoft Word, Excel, PowerPoint, and Adobe PDF files across the Documents To Go sub-apps. There's also an enriched PDF To Go app with tools to find and copy text, save as, e-mail a file, and add a bookmark. Tying up a few loose ends, the update now lets you open password-protected Microsoft Word and Excel files that were created in Microsoft Office 2007, and in other Office documents stretching back to Office 97.
The last addition in the new Documents To Go Premium Edition is a desktop app that enables bidirectional USB syncing between your BlackBerry and your home computer. That spells an end to purely manual doc management between the two screens, but we'd love to see over-the-air syncing added next.
Documents To Go Premium Edition cost $69.99 for BlackBerry phones running operating system 4.5 or higher. If you already use Documents To Go Premium Edition on any smartphone, you can upgrade to the 2.0 version for BlackBerry for about $30.
