In our previous article on Security of mobile devices we informed about recent threats and recommendations for our users.
Recently, Tim Cook, Apple CEO, made a statement about FBI asking Apple to implement a specially crafted iOS update that would allow FBI to try passcode unlimited number of times so they can crack into a suspect's device.
Without such assistance from Apple's side, FBI can try only several passcodes. After few failed attempts the iPhone is blocked for some time and eventually erased.
Apple refuses to implement any such backdoors and tools as it could pose a threat to legitimate users if such tools are in wrong hands.
This helps to picture what is the security level of passcode protected iOS devices.
