I'm confused. There seems to be conflicting information about unlocking a Nokia 6300. Some experts are saying it is not possible to unlock a Nokia 6300. Googling this question there are people/organisations claiming to be able to unlock this model. Please kindly advise if anybody has actually been succesful in unlocking their Nokia 6300 or do I really have to pay Vodafone (Australia) a lot of $ to provide the unlock key? Thanks Bob
