If you have finished your stay with your operator, you only have to call customer service to have your iPhone released. If you still have permanence and you are lucky that your iPhone is Movistar Spain or AT&T (USA) you can use liberation services like the one we discussed the other day in this post, which charge less than € 10 to free you forever.
But if you are Vodafone Spain and you have permanence it's an odyssey. I have had the need to use my iPhone with another operator and Prices for the releases by IMEI that they gave me on the webs they seemed to me abusive, I am not willing to pay 115 (or up to € 160) to unlock my mobile, for a little more I rescind the stay with my operator. Lately we have talked about this a lot on Twitter and we want to know your opinion why do you think that unlocking a Vodafone iPhone is so expensive?
After this odyssey I ask myself: Why is there so much difference between a Movistar release and a Vodafone?
