The os (opereating system) is what runs your berry. To see which one you have go to options>about and about the third line down is your os. It should look something like 4.x.x.x. I used x's because there are many out there. You do to the 8330 forum and you should see stickys at the top of the thread list. You have to use the os for your device as they are pretty much device specific.
