Questions before I unlock and flashing to WM 6.1

[ooshnoo]

Hi!

Gonna unlock and flash for the first time, but I have a few final quesitons...

1. When applying the new ROM, do I also have to upgrade the radio manually as well, or is that included in the ROM files?

2. Will I have to call Sprint and reactivate my phone after flashing the new ROM?

3. How exactly do you apply the ROM from the SD card? I may go this route as I've seen a bunch of people having issues when pluggin/un-plugging the USB cable.

Thanks fellas!!!
