I don't understand how this works, why/how are a carrier lock and a device lock related? Shouldn't one be a lock on the baseband chip and the other on the main firmware?
Unlocking the bootloader will also of course let you eliminate the carrier’s bloatware that they get paid to install and load onto it, including the things that they shoved all the way into the Android “non-disableable” list.
Tracfone called this “cellphone trafficking” all the way since the 90s when people would buy their loss leaders, flash ‘em, and flip ‘em to third world markets for top dollar.
Comedy gold. This is up there with "you wouldn't download a car", or "insurance fraud increases your premiums" in the hall of fame for "this isn't even a crime, but it makes the company sad so it's the consumer's responsibility to police".
For years, carrier lock on iOS devices was simply a software switch. In a lot of devices, still, if you have an unlocked boot loader you can run patched baseband firmware that doesn't care that it hasn't been told the magic numbers to unlock itself.
