If you are reading this at a sensible hour (i.e. not near midnight) then you will now be able to unlock your O2 iPhone completely legally and, perhaps better, completely free of charge! O2 lose their exclusivity on 10th November when Orange iPhone’s start to go on sale and it is clearly not a coincidence that this is also the date that you can unlock your iPhone on!
Pay Monthly customers can unlock their iPhone, free of charge, at any point during their contract but they will need to pay the remainder of the contract (either monthly or in one lump-sum). Pay and Go customers will need to have had their iPhone for a year and will need to pay £15 for the privelege.
For more information and to apply to have your iPhone unlocked please go to O2′s Unlock my iPhone page.
