e-mail settings

I recetly purchased a bb8703e from a private party, (used)

Everything I got working, except, when I went into e-mail settings, and tried to hook it up, it asked for my pin/esn, it tells me the pin is already registered and I have to enter id/password. problem is, i dont have either.

Can anyone help me please?

Ask the original owner to release the Pin/IMEI from Verizon. Alternatively, call Verizon, and explain that you've bought the device, and need the Pin/IMEI release from Mr/Mrs Whatever their name is.

Once done, you can then activate the device on your account, and thus get emails...
