Im trying to unlock it but you need to use ibrickr to free it (Thats what im trying to do, im not sure what firmware i have on the iPhone atm.) Then you need to upload anysim for example to unlock it, don't you?
I should also tell you, im wanting to restore my iPhone to 1.02 because ibrickr shows the following message.
"Looks like you need to download the iPhone firmware. Fire up iTunes with your iPhone plugged in, and hit the Restore button. Once the download starts, unplug your iPhone. When the download finishes, click away the error message in iTunes, and close iTunes. Plug your iPhone back in, and click Check again."
Cheers.
