First, the article several times mentions an iPhone, and publishes
a picture of something else. See, it is generic.
Second, there's a paradigm shift here that hasn't penetrated the
wit of J. Random Luser. A cellphone is not like an old fashioned
wired phone. It's a computer in your pocket, so it has hidden
files, and it can be hacked.

| At least here in Ontario, the courts have ruled the police need a warrant to
examine one.

What the recovery software does is read the phone's flash memory (including
the "empty" areas) to read all the files. "Deleting" a file doesn't remove it.
It just removes the directory listing. The actual data is still there until
*all* the free space has been used up and the phone needs to re-use some of the
previously "deleted" space. It's like putting old paper files in a box next to
the shredder, but not actually feeding them through until you run out of space
to put new ones. You can just reach into the box and pull out the old
files.
What people really need is some way to actually "shred" the
data. That's really hard to do with flash memory though. The flash memory
controllers go to great lengths to avoid unnecessary writes as flash can only be
written to so many times (effectively, it wears out). Also, once the flash
starts wearing out existing data will be moved before that area fails
altogether. However, you can often still recover data from areas marked as "bad"
if you try enough times. That's done at the memory controller level, so I'm not
sure that a purely software solution is even possible.
To be honest,
there's a similar problem with modern high capacity conventional hard drives.
There is so much error correction built into them that is not visible to the
operating system that actually deleting data requires physically destroying the
drive platter.
