USB accessory mode.
Before we look at this screenshot
and have a conversation about this,
things that you need to know this was introduced in 11.4.1.
In iOS 12, it immediately disabled the USB port
if the device was locked.
If you simply press your lock and your device is idle,
USB lockdowns are in place, meaning
that if you go to plug it in, you can't just trust it.
You have to enter the passcode in order to trust it.
Now, I want you to look at this picture.
If you read the words that are under it,
it says "unlock iPhone to allow USB accessories
to connect when it has been more than an hour
since your iPhone was locked."
This is actually what it looks like when it's turned on.
Now, this is where I truly believe
Apple wants the correct people to get access to these devices.
I know that Apple does support law enforcement operations.
However, they also want to respect user privacy.
This is a reverse switch.
If you make it green, you're actually turning it off.
If it's turned off, it's actually on.
So read the words.
It's kind of strange.
Erase data.
If you think back to the news with San Bernardino
and the active shooter that went in,
the whole FBI versus Apple thing came about.
And FBI was requesting from Apple to unlock that device.
And the reason they wanted it is, they were afraid
that erase data was turned on.
If erase data is turned on, 10 failed passcode attempts
will wipe that.
This case happened before UFED Premium was out
and before GrayKey was out.
If this is turned on and you use GrayKey or Premium,
you will not erase the device with brute force attempts
that are running against it.
