I made some changes to my desktop; as a result, for some reason, ActiveSync doesn't recognize the PDF format as one it can transfer to or from my Sprint PPC 6700. I have been using Adobe's free Reader for PPC. I have tried uninstalling and then reinstalling (to my storage card) without success. It seems to me I had this problem before, and that in addition to uninstalling the program, had to go in and manually delete some things. Does anyone know of a way to do this? Or of a different free reader that is as good?
