I have a blackberry torc 9800 and I am very ametur with computers but I need to know how I put music in my phone through something like itunes or frost wire, or lime wire?

We will NOT help with either frost wire or lime wire as they are used for piracy and copyright infringement, especially music.
They are riddled with malware and viruses and best avoided.

Whatever you choose you will need to install the blackberry manager on your machine,
This explains further what is required.
