You can generate a
HashInfo file for your device here. This file will let you defeat Apple's third-party
application lockout by enabling open-source and third-party tools to hash databases for your phone.
If you have used iTunes before on your device, you do not need this file. Only users who cannot use iTunes or do not wish to install it need to use this web generator.
Once you have downloaded this file, mount your iPod or iPhone (if you have not done so already)
and locate the
iPod_Control folder (whichever exists). Locate or create the
Device folder within, and move the
HashInfo file there.
Please ensure that the file is named
HashInfo.bin. Apparently some browsers like to do this.
