The dispute between the FBI and Apple over an iPhone connected to the San Bernardino terrorist shootings came to an unexpected end earlier today, as the FBI revealed it had managed to break into the phone without Apple's assistance. Details of how exactly it achieved this remain unclear.

"It remains a priority for the government to ensure that law enforcement can obtain crucial digital information to protect national security and public safety," said the Department of Justice in a statement, "either with cooperation from relevant parties or through the court system."

Apple just issued a response of its own, and we've reproduced it below.
