Gevey sim unlocked iphone 6
I am not familiar with unlocking and want to know if gevey sim or similar chip based unlocked iphones can be reinstalled from itunes backup or upgraded without losing the lock?
Secondly, i have seen many ads proclaiming permanent unlock of iphone 6 etc. Do they work or are they good until phone is reloaded?
