    Backup is for weak people.

    Open firmware, extract rootfs (the biggest file). Get the proper key (from PwnageTool or hxxp://theiphonewiki.com/wiki/index.php?title=Firmware). Decrypt rootfs with dmg2img/vfdecrypt suite (hxxp://vu1tur.eu.org/tools/). mount and grab your file.

    /path/to/vfdecrypt -i path_to_encrypted_dmg -o decrypted_dmg_name -k rootfs_key

    decrypted_dmg_name will still be a dmg, not an iso. To mount it you should either use a tool that understands dmg out-of-the-box, or convert it to iso, using dmg2img:
    /path/to/dmg2img -i decrypted_dmg_name -o iso_name

    iso_name can be mounted with whatever tool you want. In Linux, just use (as root):
    mount -t hfsplus -o loop,ro,offset=0x9000 iso_name mountpoint

    Perhaps you used the wrong key? The first bytes of a (correctly) decrypted rootfs should read: 78 01 73 ... in a hex viewer/editor.
