I have revirginized usig modmyi guide, but when triying to use iNdependence.app, the app allways blocked. So I try to desactivate my iphone, and... it is now desactivated!!!
Itunes won''t recognize it, but strangely I can still access to it via wifi and ssh...
FINALLY! I found someone with the same problem as I have! I did excactly as you described, and my phone is also deacivated, and iTunes does not recognize it!
