Hello. I've bought an iphone 5s under the firmware 9.2.1 and I want to jailbreak it. According to some web pages I installed pangu and raig9 but nothing worked. checked some forums and I discover that isn't jailbreakable (?). Tried to use the app store and this one needs my bank card information in order to complete registration (!?) Is this phone jailbreakable please? This product sucks really. Thanks.
