Yes it does support these file types. Through the Blackberry download app, you can get all these if you want. Adobe has an app for viewing PDFs but it's got a little hefty price tag for a phone app (I think so anyway ): $14. Cerience has better ratings for their reader, but theirs is $15.

If you go into the Applications folder inside the Blackberry menu, there is a "lite" version of Excel, PowerPoint, and Word. These are free and included, but you have to pay for the full versions and all the features. I think these are Cerience apps too.

The only question I have related to this curve 8900 is, does it support PDF files and excel sheet. I would need this on a regular basis, so before going ahead and garbing one, please let me know? While coming across its specifications, I am unable to find that it has Microsoft editor or not? I would be grateful if anyone can help me to get this information.
