I have recently bought a used blackberry bold originaly on vodaphone, it has been unlocked and i am now using it on O2 pay as you go. I am about to order the tombile sim only plan which includes blackberry email and internet booster. Do I need to de-register my phone so i get a new pin or can i put the sim in and start using it straight away..
