We are using Blackberries to display PDF reports. Here are background details on the problem:
We convert TIFFs to PDF for one of our applications, and have had mixed results with BlackBerry PDF viewers. These were our results.
Working
The following PDF readers worked for our purposes:
RepliGo Reader v1.1.1.1 - $19.95
Works fine.
DataViz Documents To Go Premium Edition v1.003.001 - $49.99
Works and includes a word wrap option to get the current zoom level to fit the available screen width, by moving text onto subsequent lines. Might fit your needs.
Non-Working
The following PDF readers did not work for our purposes:
BeamReader v1.0.8 - $17.99
BeamSuite v3.0.2 - $49.99
These couldn't open our PDF files ("Unsupported document format"). In addition they did not register as a PDF content handler, required for our application.
MasterDoc - $19.95
eOffice - $29.95
These also did not register as a PDF content handler. We had a range of problems with these, including installation issues, and not being able to open any PDFs at all.
