Hello!
My operator is offering me to unlock my iphone4 for a price around 50 USD
And my question is, how can they permanently unlock the phone without any apple firmware-update "deleting" it? (like the Ultrasn0w unlock)
They must have a very simple way to unlock it, but I don´t understand that the hackers of Dev Team can´t go "past" these firmwares updates without the unlock getting removed.
How does this work? :/ Should I pay for unlock?
I am confused
Edit: How can "operators" unlock 4.0.2 ?!?! O__o
