Deskfinder is something I’ve long wished for– a way to rapidly search and view data on my desktop from my phone.  A free beta for Blackberries is currently available.

From the product page:

DeskFinder Mobile Application brings all the power of famous Google Desktop to Windows Mobile Pocket PC and RIM BlackBerry devices.

DeskFinder allows users to search and download text from emails, chats, Microsoft Word documents, Excel spreadsheets, PowerPoint presentations, PDF files, Web history and many other files being miles away from their home or office PC.

I haven’t installed it yet but the initial reviews on Blackberryforums look positive.
