Oh dear oh dear...
here's what i believe has gone on....
apple produce the iPhone... get lots of money from AT&T to keep it exclusive to them...
What is the best way of protecting that income?
They have made people afraid to hack the firmware... who realistically is going to go out in the next couple of months, buy a iphone and hack the firmware? who is ever going to do it now that they know they could end up with a brick.
I would not even be surprised if the hacker group that developed the hack was funded by apple.. not only that, how much money had they made from the hack?
I was always a bit suspicious about the way they sold the hack. lots of little back street shops who deal in unlocking phones will have a big stack of licenses for unlocking iphones they will probably never sell now..
if the hack altered the part of the firmware which uploads the firmware, then i can understand how the product was made into a brick...if not, then apples firmware update must contain malicious code.
anyway, is it not common practice for a base version of firmware to be held in ROM to replace the existing firmware if it became corrupt? the cost of this would be minimal, and would in the long term cost less than shipping products back to base for a flash... you could also say that not having this feature is a design flaw,
