So I read most of the suggested articles for installing a ballistics program on a BlackBerry, but most on this site were incomplete or not free. I found a neat little program that features; pocket pc, trajectory tables, moa range card, mil info and what not. All in all a decent free ballistics program. I did this on an 8520 Curve but most BlackBerry's with sheet to go should run this. Steps 1. Download Excel Ballistics Calculator to your home PC. Free Ballistic Calculator (FREE Ballistic calculator) 2. Make sure your BlackBerry is running 4.5 or newer operating system, you will need the "sheet to go" to run excel files. PM if you don't know how to do this. My BlackBerry had sheet to go but here is where you can get it http://www.dataviz.com/products/bundle_BB_select.html?redirect=rimos45 3. On your phone go to Settings > Options > Memory and make sure "Auto enable mass storage mode when connected" is turned on. Some BlackBerry's may not have this option under memory, but search around you will find it. 4. Connect your BlackBerry to your PC using the USB cord. Now go to My Computer > BlackBerry > BlackBerry > Documents. Now place the ballistics calculator in the documents folder, either use copy and paste or drag and drop the program from the desktop. 5. Disconnect your phone and go to applications "sheet to go" search through your documents and find FBC-V3. Now there are several windows you can view by using the menu key and clicking on worksheets. Enter in all your ballistic info and save your profile. You can set up as many loads as you like, just make sure to name them properly. Also the Pocket PC mode is great after you enter all your info in. Input the particular range, slope, wind, temp, psi and it will show you the MOA needed to dial in. Perfect for a free program! Any questions or problems just ask, I spent quite a bit of time trying to do this free, since I do not have the data plan.
