Vogue GPS 3.02 Kitchen (w/ NEW Sprint Leaked ROM)

[FastRX8]

I'm updating my kitchen right now.
I would like to try the new radio. I'm current on the 3.37.10 radio, and it works fine, but I wouldn't mind seeing an improvement. This rom has 3.37.15 right?

Please correct me if I'm wrong.
To upgrade the radio, I have to;
Download and the leaked rom from here - http://ppckitchen.org/misc/V3.02.rar
Go into bootloader (of course this assumes I'm on 2.31 bootloader)
Run the EXE from the rom.
That will update the radio as well as everything else.
Then I can use the kitchen to create my own stuff, but the radio will still be the latest version.
