Just to let you guys know, if your phone has "documents to go" you can go to the thread about ballistics program and download "the thing". It works on my phone, although it has some extra stuff I don't need. I trimmed it down to the cartridge page, ballistics page, and another dropsheet. It works well although the small screen size makes it a bit difficult to navigate. If your phone will run something made specifically for it, it would look better but I'm not sure if it would work better.
