iPhone Update Appears To Brick Legit Phones
It is not clear exactly why this is occurring, as Apple has yet to comment on the problems. But the rash of reports from those who have not unlocked or modified their phones indicates that whatever the Cupertino company is doing to 'brick' unlockers may have unintentionally taken out some of its law-abiding customers.
A closer look at the iPhone support forums show many of the issues deal with loss of data, which isn't the same as bricking, where the device is useless. However, we were able to find at least two instances of actual bricking without looking very hard.
