Honestly not sure how this is legal given that the software is not fully baked when the devices ship. That is, people were getting PT2s when there was no way to test the touchscreen because the OS didn't support it yet. Same for speaker.
My guess is that if you got a bad unit and discovered it later when the software was updated, they'd probably swap the unit for you. That seems like more of a no-brainer than the screen crack replacements they're apparently doing.
