By the "restore iTunes symbol" do you mean a USB cable and the iTunes symbol? If so the device is in Recovery Mode and the device has already been erased and it needs to be Restored using iTunes. If your Dad had a backup you can Restore from backup after the iPhone is up and running. Follow the link for instructions > http://support.apple.com/kb/HT1808
If this is not the case please post back and we'll try and help.
