Sorry if this is a FAQ - I've done quite a lot of Googling and am bamboozled with all the unlocking services and warnings about using some of them. Anyway, I have just received a new Xperia Ray which is locked to Orange and we want to use it on the BT network. What is the best way to unlock it? I don't mind paying a little extra for a safer solution. davinciteam.co.uk seems to be quite well thought of and costs 20 Euros for a SIM unlock. DavinciTeam | Creative Mobile Phone Applications Is that the best option?
