Motherboard: Cops around the country can now unlock iPhones, records show

Motherboard:

Police forces and federal agencies around the country have bought relatively cheap tools to unlock up-to-date iPhones and bypass their encryption, according to a Motherboard investigation based on several caches of internal agency documents, online records, and conversations with law enforcement officials.

And:

Regional police forces, such as the Maryland State Police and Indiana State Police, are procuring a technology called ‘GrayKey’ which can break into iPhones, including the iPhone X running the latest operating system iOS 11.

Is this whack-a-mole? Will Apple be able to change iOS to break GrayKey? And, if so, how long will it take for GrayKey, or another technology, to ship a replacement?
