If you are the original owner of this phone, you are the only person who can get it unlocked by O2 for free. Also, £130 for a 3G without the charger bit is a little pricey. I sold mine over a year ago for £150 also without the charger but with case / screen protector etc, plus it was in a much cleaner condition. I remember a couple of 3Gs went for around £150 here recently.
