Lost my iphone. Will the thief be able to reset without losing data?
Hello! My iPhone 5 with iOs 7.0 was stolen yesterday. I have enabled Find my iPhone, but it's been offline for 20 hours, so i'm assuming he has reseted it. I am very concerned about all the information i have on the phone, pictures of my wife and kids etc. I remotely created a code on my iphone with Fmi, but the thief still called my friend AFTER i had done this, which gave me an expression that the code was not working. The phone has now been offline as mentiioned, and my question is:
1. Will the perpetrator be able to block find my iphone without factory reseting and losing all data? Can he make the phone stay offline and still get access to all my pictures and information?
2. Will the phone come online if he changes the sim cards to one of his own?
3. Will the phone come online if he connects it to itunes to factory reset it?
And most of all: I'm very concerned that the code did not work, why didn't it even though i made a code? How was he able to call my friend? I'm not so worried about finding the phone, i'm just worried that my personal life is open for everybody else.
Thanks!
iPhone 5, iOS 7.0.1
