Archived from groups: alt.cellular.nextel (More info?)

Recently (3 Days ago) I activated a Blackberry 7510. Everything is going  
well except that when I go to the Blackberry site and try to setup the  
Blackberry email I get a message saying
"The PIN and IMEI you have provided are already associated with an  
account within our system."
The Blackberry division of Nextel appear to be clueless. I told them I  
bought the Blackberry from a co-worker and for some reason they cannot  
clear this up. I am not sure why they can't just cancel the account so  
that I can set my Blackberry up for email They want to know more than  
the pin# and IMEI#. I would think that that would be enough info. Anyone  
shed some light on this situation or tell me how to get in touch with  
someone that can help me? Thanks.
