Any phone can be hacked.
Really? Where are all the hacked iPhone exploits? If you can phish the user, get his passcode, then yes. But to actually get into a modern iPhone? No. The one they hackers got into from the San Bernardino Terrorists was an iPhone 5C, using the older SoC which was developed for the iPhone 4S from two years before instead of the far more secure iPhone 5S that was released at the same time as it was which had the TouchID and the Secure Enclave, yet even the 5C kept every one out for months and ALL iPhones from the 5S through the 6S plus have yet to be broken into. They are protected by 256bit AES Encryption. Unless you can find out what the user's passcode is, you are not going to decrypt that data in anything less than astronomical time frames.
You can make such simplistic statements as "Any phone can be hacked," Laz, but you lack proof. The FBI has hundreds of seized iPhones they'd like to get into which they have been totally unsuccessful in hacking. . . even after getting into the San Bernardino terrorists' iPhone. Police departments across the country asked for help in getting into the thousands of various vintage iPhones they have but they got just crickets in response from the FBI, because it was expensive to crack into an OLD less secure technology iPhone and because it was NOT a trivial thing to hack into even that, and the newer ones are at least a magnitude or two even more difficult to try hack into.
Why do you think they are trying so hard to REQUIRE back doors into these devices? It is not to get back doors into Android devices. Backdoors into those they've had for years.
