windows office: If your BB Curve comes with the 4.5 operating system then it will be on there. If it does not then you will have to pay about $70.00 dollars for it. Then you have it on your computer / laptop - connect the laptop to your phone via USB cord then run the application loader software to put it on your BB Curve. Unfortunately, I am with Sprint and they have the 4.3 operating system on their BB Curve 8330. So, I am hoping they will allow us to upgrade soon. Different service providers will not allow you to just upgrade - it is like they optimize the operating system to fit the particular phone and their software they run off their servers.|||Robert F is right about needing the 4.5 OS, but you can download it right now for free. It will include Docs To Go which includes Slideshow to Go (opens Powerpoint docs) and Word to Go. I also suggest you snag Beamreader for reading Adobe .pdf files.
