BlackBerry Swiss Army Knife (BBSAK) is an invaluable free tool for BlackBerry users. It is a small Windows desktop application, which replaces JL Cmdr, and gives you a greater level of control over your BlackBerry. BBSAK helps you backup and restore your BlackBerry, add and remove software, and take screenshots from your device.
Even though you can perform OS upgrades and add or remove applications using the BlackBerry Desktop Manager, it can be cumbersome. BBSAK allows you to plug your BlackBerry in and get right to work. It also allows you to quickly see all of the software installed on your BlackBerry, and view the Event Log to identify problems with your BlackBerry OS and applications.
BBSAK is a very powerful tool, and should be used with caution, especially when removing or installing CODs, wiping your BlackBerry, loading the OS, or performing a factory reset. Proceed with caution, and make sure to backup your BlackBerry before attempting to make any major changes to your device.
