Blackberry Tour 9630 software in GPS technology and devices Posted June 3, 2010 I tried Cachberry it works good but is a very big program. I ended up going with BlackStar it is free and is a small simple program to us. i'm using BlackStar now. Seems like a good, free app. i'm new to caching so not sure what features the app could be missing. Any opinions on Geocache Navigator for VZW app?
