I'm very curious about this too. Above all, in case there is some truth to all this, how does one restore the iphone to factory condition? I've heard that a simple restore doesn't do that, is that true?
I wonder if this is just a scare tactic to scare potential unlockers off? Apple has sold countless iphones to customers who they knew did not live in the US (I've witnessed this in the Apple Stores) and who they knew was not going to sign up with ATT. If Apple deliberates ruins these iphones, I'm sure there will be a huge backlash and
PR disaster.
Anyway, curious to hear what those who understand the unlocking software better think about this? Is there reason to be afraid?
Cheers!
