RepliGo is the flagship product from Cerience. The software, which can be installed and administrated on BES or via subscription to Cerience, allows users to view a wide variety of files on their BlackBerry. PDFs, Word, Excel, and PowerPoint docs, rich text files, faxes, images, and more can all be accessed directly from your phone. You can even print to an HP PCL Bluetooth printer or fax documents without sitting at a computer. It plays nicely with any other attachment services present on BES, and works with Microsoft Exchange, Novell GroupWise, or Lotus Domino.
