Hello people,

You can upgrade your blackberry OS or firmware or whatever its called, the advantages are numerous, your machine runs faster, smoother and it even resolves any problem your BB must have developed, eg hanging, short battery lifespan, improves performance greatly and adds new features.
How to do it? Well, download the latest Blackberry Desktop Manager from blackberry offical site to your PC, its like version 5.0.1, plug in your BB to your laptop or PC, it scans your BB and gives you applications on your phone that needs upgrading. Follow the prompt and you are on your way. For those with 2010 model BB, you are running on latest OS already so you don't need upgrading.
WARNING - Ensure you have a reliable internet connection cos long internet breaks may harm your phone.
NEVER NEVER disconnect your BB while the process is on or else forget you have a Blackberry phone.

The whole process takes like 1 hour but when its finished your phones comes out like a car that just had new engine.
