deep, deep, deep, DEEP under cover. :-)

Now...the question is, will some sort of authorities be after Dan under the DMCA for unlocking his phone.

Someone needs to do this for the Toshiba Excite line of tablets. Awesome work.

Nice work.

Can the TZ kernel be patched in a software update?

Beautiful example of how state of the art encryption with hardware support is just like putting a deadbolt on a french door.  You don't really need to rip out the door, just break the glass.  Everything can be broken.  It just depends on how badly you want it.

We still can achieve freedom to use what we bought however you see fit. Fortunately, it's still only a matter of both will and skill. :)
