i am thinking of buying a used blackberry 8900.so i want to know if there is any way to check if the PIN is registered and has ever been used, cause i wouldn't like people that i don't know of to have it.secondly, can anyone describe me a way to erase all the data (applications, settings, etc.) of the previous owner, so as to have a totally "clean" device??
thank you very much but i have a question.if the phone is not branded to any provider, where/who am i going to ask if the PIN has ever been used?for example, one i found says the phone has never been used, but how can i be sure of that?
