The free calculator came from http://www.tucows.com/preview/132634
, I have been using a Palm for about 5 years, then a treo 270 for about 2 years and I guess I am spoilled as 2 calculators came with the treo. I am very dissappointed in how complicated the BB is to use and how few downloads there are for it. The keyboard on the treo is so much easier to use as the layout is the same as the layout on my pc.
I will try the above to get it on my bb but first need to know what is a "DM".
