> Google phones allow re-locking the bootloader with your own key, except it still results in a warning during boot

The warning is a great thing for security: I'd appreciate it if my phone showed me that warning after I've surrendered it to the border control agent (alternatively, a sketchy repair shop), or bought it pre-owned, or if I "lost" it and gets returned to me.

Let's start with the fact that unlocking the bootloader wipes the entire /data partition to prevent this exact scenario from happening.

That'a a great point, and you're correct on the impracticality of the evil-maid attack. However, my point remains when it comes to less-than-honest repair shops or second-hand sales where wiped devices are not suspicious. I want to know if my bootloader/kernel may have been tampered with before I am able to trust the apps.

I wish I could have thought of that argument on a previous discussion about iPhone/ iPad jailbreak discussion thread
