No, bigbob, Apple has not. That claim has been debunked completely. Apple does not have the capability to decrypt the contents. In the past they were able to provide the contents that were not encrypted, and never unlocked the portions that were encrypted. This has been posted numerous times on FR. It is the Apple Law Enforcement Guide to what they CAN provide in response to a search warrant:
It is pretty straightforward. For iOS 4 through iOS 7, they can provide those data that are listed. For iOS 8 and above, they can provide nothing, because it is all encrypted and they simply do not have the key to the encryption.
For any iOS 1 through iOS 3, there is no need for Apple to do anything, as everything is unencrypted, and the police already have the tools they need to unlock devices using those versions of iOS.
The fact is that no one CAN decipher something encrypted to a 256 bit AES standard encryption without the original key.
Without that key, it is, for all extents and purposes, unbreakable. The laws of mathematics do not change for Apple or anyone. It would take them just as long as it would for the NSA. Without the key to decipher the encryption, which has a key made up of at least 132 characters if the passcode was just four numbers, it would take 5.62 UNDECILLION (5.62 X 10195) YEARS using the fastest supercomputer available today to try every possible key!
I think the contents of that iPhone would be moot by the time anyone found the correct key, don't you?
