Class is in session... Today's lesson will be on how to downgrade the OS (operating system...aka firmware aka device software) on your BlackBerry. Some of you may have chosen to upgrade to 5.0 or some other OS that isn't just right for you. Luckily, BlackBerry smartphones are one of the easiest (in my opinion) to downgrade. I chose to upgrade to 5.0 on my Curve 8900 (using Desktop Manager 4.6) and I want to go back down to 4.6.1.168 (my favorite).
