Splash Screen numbers meanings

[rynosims]

I have searched, and can't find what I am looking for. I am attempting to do the upgrade for my Alltel 6800. I have had much dificulty with this upgrade. I was just wondering exactly what the numbers in the lower right corner of the splash screen mean. Mine are as follows:

R 1.32.00
D 3.35

Is R the radio version or the ROM version? And what about the D? Really just curious. I finally got the Sprint official to run, and am now attempting to run DCD's kitchen to install the Alltel stuff. I hope this works this time.

Thank you in advance for the help!
