While this case might have ended, but the battle isn't over yet. Via Matthew Keys on Twitter:

"There are 6 other cases where Apple is still fighting the DOJ re: unlocking phones"

^ Link includes an image with 7 other cases where Apple has either objected to warrants, 2 that are still in process.

The most interesting one is the last, which involves an iPhone 6+ running iOS 9.1. It's not yet clear whether the zero day that allowed the government to access the San Bernardino phone also works on the iPhone 6, which has a secure enclave (unlike the San Bernardino phone). There are some other iPhone 6 and iPhone 5S devices in the list too running older versions of iOS.
