Well shazam! That's why I love this place. Always learning something new.
I wasn't real clear on the conversation, so I attempted to clarify it in my head with a little research, and loved the result!
Treos run WM6 Pro, which I thought already contained Office Mobile 6. The conversation led me to believe it was a separate app. So I went to Microsoft to look and saw that 6.1 was a free download for users of Office 6.
I figured I'd give it a shot and downloaded the upgrade to see if it would run. Got it here:

I plugged in my USB, ran the upgrade, and TA DA! I'm on Office Mobile 6.1.
So, the answer is: YES IT IS A FREE UPGRADE.
First upgrade to WM6, then download and run the Office 6.1 update.
