FBI wants Apple to make new OS version and install it on the iPhone recovered in the San Bernardino caseGetty Images

The tussle between Apple and the Federal Bureau of Investigation started more than a month ago when the FBI reached out to the California-based smartphone maker to decrypt the iPhone that belonged to San Bernardino gunman Syed Farook. The FBI sought a master key to unlock the phone using as many passwords as possible. Apple was firm that providing the key would lead to a major security concern, exposing user data to cyber criminals.

A lot has happened in the case since then. Many technology firms including Microsoft, Facebook and Google, came out in support of Apple. Here are some of the famous and interesting quotes from both the parties, Congressmen and other well-known personalities, on the case.

"Specifically, the FBI wants us to make a new version of the iPhone operating system, circumventing several important security features, and install it on an iPhone recovered during the investigation. In the wrong hands, this software — which does not exist today — would have the potential to unlock any iPhone in someone's physical possession." Apple CEO Tim Cook

"We're asking Apple to take the vicious guard dog away and let us pick the lock. It's not their job to watch out for public safety. That's our job." FBI Director James Comey

"I have no idea. I don't know. I don't know if that would work. I have no idea. I'm not sure I even fully understand the questions ... I did not ask the questions you're asking me here today. I'm not sure I even fully understand the questions. James Comey

"Before these devices came around, there was no closet, basement or drawer in America that could not be entered with a judge's order. It's not (Apple's) job to watch out for public safety. That's our job." James Comey

"All you've been doing is saying, 'No, no, no, no. The thing is, you ask Congress to do something, and I asked you what Congress should do. You said we have nothing. Jim Sensenbrenner of Wisconsin

"Can you appreciate my frustration with what appears to be little more than an end-run around this committee?" Congressman John Conyers

However, the best line came from US Republican presidential election candidate Donald Trump: "To think that Apple won't allow us to get into her cellphone? Who do they think they are?"
