DevTeam: Apple didn’t have to brick unlocked iPhones
Little comfort to those who face bricking their unlocked iPhones or languishing on old firmware forever, but the iPhone DevTeam have been pretty unequivocal at accusing Apple of taking the, let’s say, AT&T pleasing option when it comes to constructing their upgrade. As they told Gizmodo:
“Apple has multiple ways of upgrading the [firmware of the] baseband [radio chip] without committing a 500,000-phone massacre. First, they can issue a secpack [security pack] for everything in the firmware. They could simply issue one of these to restore the value if a regular token is not detected, thus rewriting this part to its original state. This process would most likely defeat any unlock available, Dev Team or iPhone Sim Free, without bricking the iPhone in any way. New firmware updates could also employ new firmware which closes the loophole that allows the use of a secpack for other operations. They could make this method of updating even resistant to tampering or abuse for a unlock. The possibilities are there”
