    Hi
    I have iphone 4 16gb 6.0 factory unlocked, normally I am using three IE sim card, I tried to use another mobile provider sim card and I see sim card failure... I' ve checked 5-6 sim cards vodafone, tesco, o2, even another sim card from three IE network and doesn't work as well, all this cards works on another iphone 4 unlocked software 5.1
    I did restore and no change?! I did restore with inserted another card for example vodafone works fine but as well only with this one card?!
    I' ve been trying find out what is wrong, after 2-3 restore give up!

    Does anyone had the same issue?
    regards
    Pawel

    100% is unlocked

    Did work before 6.0 update, I did use two polish sim cards before and did use this iphone over one year in o2 then I moved to three. Now does not work even with another sim card from the same network, only one card works!

    Very weird.
    Factory unlocked iPhones don't lock up with restores or firmware updates.
    So somehow it's not unlocked any more.
