Upgrade blackberry 8800 OS

[nsb1]

I want to be able to use Pandora on my Blackberry 8800 but when I go to the Pandora site it says I need OS version 4.3 or higher. My blackberry is using OS 4.2. How do I upgrade the system?

Thanks for the link. I forgot to include in my question that I am using a Mac. This link seems to be for Windows. How do I use a Mac to upgrade the blackberry OS system?

You can't. You need Windows.
