I bought a blackberry off of ebay, and I'd like to set up my email through the Blackberry Internet Service but when I go to put PIN and ESN in it says I've already registered. Is there any way to get past this and create a new one? Also, how long does it traditionally take to activate a new BB w/data on verizon?

you will need to contact seller and get them to unregister the pin. RIM may be able to help you but original owner is best

The PIN and ESN numbers are unique to that particular Blackberry, like it's fingerprint. Not changable.
