I bought a BB 8330 from someone on Craigslist (flame suit is on). I called Sprint to see if I could switch my number frommy phone to the BB. Turns out the ESN is registered by a corporation that has not released the ESN. I asked if the phone was reported stolen and the guy said no. Am I up the creek without a paddle? Sprint said I couldn't activate it without getting the ESN released. All I want to do is switch my service from the current phone to the BB 8330. Wish I had learned about this site sooner. Thanks for any help.
