    I'm just wondering, if Apple really hates jailbreaking that much wouldn't they add a new hardware that would detect it and be saved to a file where it couldn't be deleted?

    the iPhone checks for this type of code execution in the kernel during each boot; part of the (untethered) jailbreak process is to patch or remove this integrity check. If you've seen an iPhone with a white screen at startup, that is an example of the kernel recognizing unsigned code (a jailbreak).

    Recall that a tethered jailbreak requires you to rejailbreak every time the device is rebooted, this is when the kernel checks for unsigned files. A tethered jailbreak is one which the device was not altered to remove this check, so the check must be validated by a computer (easier said that done).

    O alright, but what about this, Apple installed like a small memory somewhere in the device where it records when it goes into DFU, restore, and when something is altered on the device. Then when we go into the Apple store asking for a exchange or repair apple scans that part and finds out we were jailbroken.

    That's kinda what a jailbreak is.

    Apple tries to stop those applications and processes from running and being executed.
    The Dev Team and others find ways around it.

    So, in a sense, they've been trying on every iDevice they've made.
    ...Just hasn't worked yet

    That's kind of what the BootROM is; only it has more than just integrity checks (gives boot instructions of how to turn on, what to turn on at bootup, exe). You're suggesting though that a hardware chip scan at least 16GB of space at each boot and record a log of modifications made to a device. This would be impractical because of the time it takes for a scan of 16GB to take place. Instead, Apple uses the kernel to kinda do what you said but on a smaller scale.

    It also could be illegal, for privacy concerns, wouldn't it?
