Well, my boss make sure to buy all the blackbery development books available and I like these ones:
- Beginning BlackBerry Development by Anthony Rizk - excellent if you are new to blackbery development
- BlackBerry development Fundamentals by John Wargo - If you want to learn what happens behind the scene, not much code but great for conceptual definitions
- Advanced BlackBerry Development by Chris King - As the name goes Advanced..!
- Learn BlackBerry Games Development By Carol Hamer And Andrew Davison - Although this book focus in game development you can find invaluable tips and tricks here.
- BlackBerry Java Application Development by Bill Foust - Great introduction and intermediate level
