Graykey is a box that can unlock any iPhone including the iPhone X. There are 2 variants of the Graykey box available for sale to law enforcement. One is $15,000 and the other is $30,000. The cheaper version has a limit of 300 phones which equates to $50 per device. The more expensive one is unlimited. One writer pointed out that this device exploits security vulnerabilities that could eventually be patched by Apple leaving the device’s future effectiveness in question. For the moment, however, authorities have the upper hand over iPhone users.
