It does not say anything about another network it simply states, "Cannot create account: An account already exists for this blackberry device. Please log in or contact alltel at 1 800 255 8351." I tried to retrieve what ever I could off the Alltel.blackberry.com website however when I enter my pin it states no username and password exists please create new account by logging into the BIS. Also I believe this Storm was setup on a BES not a BIS by the previous owner while it was on Verizon. Can that cause a problem?
