I have the iPhone 4s and have it on a 24 month contract with orange meaning my phone automatically locked to the orange network the first time i put my sim in it. The problem is, i'm moving to study abroad for a year and want to take my iPhone with me.No, i don't want to sell it and buy another one as that has already been suggested but i don't want to be left paying a contract and still have to pay for a new phone. I was wondering, is there anyway i could get my iPhone unlocked so that i can put a sim from another country into it? This way i would avoid extensive calling/texting/data costs and i wouldnt have to get rid of my iPhone or get a new one. Also i want to keep my orange contract open because i will be coming back to the UK at christmas/easter/summer etc.
