The BlackBerry is slowly building up applications that let it read multiple document file formats. The latest in the roundup is from RepliGo with an upcoming piece of software called RepliGo Reader. It is scheduled for release in Q3 and should be interesting.
From the product description:
RepliGo Reader is a full-featured PDF viewer, similar to Adobe Reader for your desktop. You can quickly zoom in and out of documents to inspect the details of any page. RepliGo Reader can also intelligently reformat pages to fit the width of your BlackBerry screen, making it easy to read documents by eliminating horizontal scrolling.
Advanced navigation features are also supported. PDF bookmarks are presented in a hierarchical view, allowing you to quickly jump to any section of a document. Hyperlinks are active and integrated with the BlackBerry browser, email and phone applications. A powerful search feature is also included, enabling you to quickly find information in the PDF file.
