Apple Inc said the U.S. Justice Department’s new attempts to unlock an iPhone used by one of the San Bernardino shooters without the tech giant’s help could eliminate the government’s need for its assistance in a similar dispute in New York.

“On the other hand, if the DOJ claims that the method will not work on the iPhone here, Apple will seek to test that claim, as well as any claims by the government that other methods cannot be used,” Apple said in the letter.

If there is a flaw in its encryption, Apple wants to know what it is so it can lock it down. Makes perfect sense.
