Hi all,

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.

Thanks!

you must revirginize your phone before you can use the hypercard/hypersim.

downgrade to 1.0.2, revirginize, update to 1.1.1, activate and insert your hypercard and thats it. you dont have to unlock it
