One great thing about BlackBerrys is they rarely get "bricked" during an upgrade. If the upgrade fails or gets interrupted you can almost always just re-run the process and it will work.
You can upgrade or downgrade as you wish. If you install a new OS version and don't like it you can simply downgrade back to what you had, provided the OS install files are still available online somewhere.
