BB Curve :: Turning Radio On?

I have had a Curve 8330 in service with Virgin Mobile, for a couple of years. I have just recently switched my cellphone number to a new handset and new service provider. In preparing my Curve 8330 for a new owner (at some point), I opted to use the "Wipe Handset" function, to clean the handset of all my personal information, contacts, etc. During this process, I was advised that the "radio" would be turned off. I thought I was going to be able to manually turn it back on after performing this "wipe", so I wasn't concerned. This would seem (so far) to not work; at least - not the way I was expecting to be able to. Does anyone know how I could at least turn the handset's radio on? While this wouldn't do much good without a service contract attached to the handset, it will at least assure me that the unit is still in working order, and will work properly for a new owner.
