About 11 months ago I bought a sim-locked iPhone from my local operator. Last march I got 2 replacement iphones (first came with dead pixels, Apple sent me a second one that worked fine). However, this third iPhone is really strange regarding the sim LOCK. So, it's supposed to be locked to my operator (Movistar Spain). If I put any other spanish sim card (Vodafone, Orange), the iPhone asks to be activated thru iphone, and the process logically fails. HOWEVER; If I put my old italian sim card (from TIM, one of the official carriers in Italy that sell the iPhone), I can successfully activate it thru iTunes. That means that I can use my TIM simcard and my MOVISTAR simcard in a phone that is supposed to be sim-locked to movistar. Moreover, I borrowed a friend's iphone, also locked to movistar, and I put in my italian sim card. The iphone directly said "incorrect SIM" it didnt' ask for activation. So I reckon there's something different about this replacement iphone since it doesn't reject other sim cards (never shown "incorrect sim") but activation fails. Any explanation for this? (I've been told maybe I was given a replacemtn iphone meant for the italian market where iphones are sold unlocked - but as I've said, my iphone is not unlocked to all operators, only to TIM. I guess I would need to try a Sim card from another country that sells iphones but I don't have any at hand).
