Hey there, i got ago 1 year a iphone 6S 64GB RoseGold with ios 9.1 and i noticed ago 1 year already, that my phone turns off when soft wind bless on my phone while the weather was very warm. The provider said that my battery has to bee replaced with a newer model because my currently battery is outdated and a old model and apple delivered like 1.000 phones with this battery and 1 month after the 6S was released, apple re-made a battery exclusive for the 6S because people reported this issue alot and bla bla. Well, i had to sent back my phone for a replace. I did it. Now i got my phone back and what do i see ? WHOLE PHONE IS REPLACED. And also Ios 10.2.1 ON IT !!! I searched around google if there is any way to jailbreak and i read about a "yalu jailbreak" or something which shines to work and is also for ios 10.2.1. I found a download link of the jailbreak tool ago a few hours, but i left the site cuz i wasn't sure if its fake or not. So my question: Any jailbreak for ios 10.2.1 ? is this "Yalu" or however it is called, fake ? or real ? and what's theyr official site if its not a fake ?
