I get that. But software in flash-able firmware and software stored in flash. Tantamount to the same thing. The device is ultimately as reliant and affected by one as the other, although firmware on the iPhone is more comparable to the BIOS on a computer, in that if you mess it up, the device may not be able to boot to the point the other software gets a shot at messing it up.
So say Apple's firmware updates simply patch the existing firmware. There's the problem. The patch is incompatible with the unlock-patched firmware and will therefore brick the iPhone. But if instead patching the firmware, you just re-flashed the whole firmware with expected firmware patched, no brick. If that's the case, Apple is choosing to patch when they could re-flash the whole thing to a stable firmware. They are choosing not to do this. That's tantamount to intentionally bricking unlocked devices as they have a choice. It's not the same as devising something that discovers a phone is unlocked and then bricks it, but by choosing this method of updating the firmware this time rather than choosing a method that spares the unlocked phone it *is* tantamount to intentional.
But, typically, when you update firmware you re-flash the whole thing, anyway, so I'm not even sure why this would be an issue. Re-flash the whole thing with the new version, and other than removing anything any user has done to the firmware, nothing bad happens. Like PSP hackers: if they have hacked firmware that supports home-brew games and other non-Sony functions, and they update to Sony's version of a new firmware, it never bricks the firmware, they just lose everything they had in the hacked firmware.
This is exactly what I was saying in the last thread. It appears if Apple is just patching the parts of the firmware rather then just reflashing it. The ONLY reasoning behind this that I can think of is so that it messes up unlocked iPhones as the previous firmware updates just reflashed the firmware.
There's no doubt in my mind that this is intentional. Maybe not intentional in the fact to brick phones, but intentional so that everyone is terrified to do any sort of hacking as they know Apple is addressing its updates specifically so that it will brick unlocked iPhones.
EDIT: As for saying that Apple rarely updates the baseband and hasn't yet, you're wrong. 1.0.1 updated the baseband.
