my girlfriend accidentally upgraded her unlocked iPhone 1.0.2 to 1.1.1 and got the phone completely stuck.
I downgraded the firmware succsessfully, and activated the phone again, but always sim error.
I put my hypersim inside, and I get always SIM ERROR.
Is there any way to make the Hypersim work? I read that for turbosim there is a set of instructions to send to the phone via terminal...
Any help will be appreciated.
