The case they described said the phone had no passcode lock, so the data on the phone would not have been encrypted. In the other cases, the phones did have a passcode lock, but with 10000 possible four digit codes it takes about 40 minutes to run through all given how Apple has calibrated PBKDF2 on these (4 trials per second). I've been recommending that people turn off "simple passcode" on iOS devices and move to at least six digits. If your non-simple passcode is all digits, you are still get the numeric keypad. I've written about all that here http://blog.agilebits.com/2012/03/30/the-abcs-of-xry-not-so-simple-passcodes/ when there was some hyperbolic claims about breaking into iPhones.
