strange that it needs this to be done
"To unlock the phones for international use: if you travel outside of the Americas and use a non-American SIM card, you will need to first make a phone call with an American SIM card for 5-10 minutes to unlock the phone. There is a sticker on the back of the phone with complete step by step instructions. "
its the i model which is for international so i would think its factory unlocked..
