After dealing for hours with the iPhone I was able to repeat the whole process and downgraded the baseband correctly. The problem with the terminal giving me this: -sh-3.2# instead of this: #.
First make sure you are in firmware 1.0.2, activated and jailbroken.
Install ssh/sftp/... etc.
Then get the folder Virginizer_pack and make sure it has 12 files including "virginator.sh".
Upload it to the iPhone with Cyberduck to the /usr/bin folder.
Then make sure all permissions of the folder and containing files are set to 755.
Then you can follow the command lines described in this tutorial.
Be patient, there are many restarts to do and error messages.
Thank god I found a guy in Mexico who helped me 8 hours straight using messenger until ge got it done. He sure has become me new hero and friend!!!
Keep up the good work!
