Revirginize Your iPhone
Would you like to update to the 1.1.1 firmware version and play with the iTunes Music Store?
There was a method that i tried that involved , connecting to your iPhone over SFTP and SSH and execute some files and cheat SimFree application with the seczones on geohot server.
It´s complicated if you are a newbie ( I was stuck figiuring out some things 
) but there is a better solution for that.
If you have firmware 1.0.2 and unlocked it with iUnlock or AnySim or you Upgraded by mistake to 1.1.1 then, this is for you and its time to Revirginize your iPhone.
The tool returns your iPhone to the original condition, as if you never done anything. Hats off to the iPhone-elite team that put together the automated script. You need to install BSD Subsystem and Open SSH trhough Installer.app on your iPhone.
You should have a WiFi conecction to achieve this to dump the files on the iPhone and run the /virginator.sh via SSH
Download the script: Revirginizting Tool
Once you Virginize your iPhone you can Upgrade to 1.1.1 and then unlock with the help of INdependence and anySIM 1.1.
Are you going to try it?
