People, please help. So I bought my wife a 3gs some time ago from Apple that was factory unlocked. It has been on O2 ever since. Saw some good deals so requested a PAC code and transferred her to Three, however when I put the sim in I got No Service, then remembered that her phone died and was replaced under O2's insurance. Clearly they have replaced her phone with one locked to O2. So I quickly got on to O2 and requested an unlock, however my wife's number has now ported to the Three sim (works on another phone) and now she cannot use her phone, also I have no idea now if the O2 unlock will work, do they have to send something to the phone, if so clearly they will not be able to now as the phone has no valid sim in it!?! Really do not want to pay someone online £40 to unlock a phone that is probably not even worth £40. Anyone got any advice or help?? Appreciate your help on this.
