Can anybody help?

I have an unlocked BlackBerry 8700C, given to me in the summer by my
American father-in-law - as a sealed package. In short the sound quality of
the BlackBerry is substandard so I'm selling the device.

Now the chap buying the BlackBerry has tried to get it hooked up with
Vodafone's BlackBerry email service, but they tell him the device already
has an account.

That's got me. New, sealed to me, I've never used it with a BlackBerry
email account. Cingular don't have a record of it, BlackBerry refer me to
Cingular and I use Virgin Mobile myself, if they have a BlackBerry service
I've never used it. Vodafone tell me that the device has a "business email
account" attached to it...

So is there an easy way to find out where this account is from and how to
remove it so that the BlackBerry can be used with the service?
