Just fill in the online form on the Vodaphone website, make sure you've got £20 credit on the phone and Vodaphone will get in touch with Orange and get the unlock code for you. Can take up to 10 days from start to finish. Once the process is done, you'll get an email telling you to insert a "non Orange" sim in the handset and plug into itunes.Follow the instructions and the phone will then be sim free. (Network unlocked). Better than Jailbreaking in my opinion. You'll need to get your EMEI number from the handset beforehand.Just google that bit.
