2.13.00 radio. How do i get to a 3.xx radio???!

[DssTrainer]

I've read every sticky across the board and they all give contradicting information.

I have a new Touch. It has 2.13.00 radio on it.
I ran the ImCokeMan unlocker 0.41. I verified it was on there.
Now what?! What rom do I use to get the updated radio?! All I see is people offering roms that need to already have 3.xx on there.. but nobody tells you how to get there from 2.xx.
