I downloaded both 4.3.4 & 4.3.5 Firmware files & used Redsn0w 0.9.8b3 to hack my 4G 4.3.5 iPod Touch and when I try to open the Firmware files in Redsn0w 0.9.8b3 they don't appear in the Window. When clicking on them (not in Redsn0w) it says they're corrupted or something else and I can't extract them (though when I've tried that in the past files still didn't show up). So how can I hack my iPod Touch 4G now? What can I do to get Redsn0w to identify those firmware files? Someone please respond to this because I've been at this for ages with no prevail. NOTE: My computer couldn't exactly recognise the files by image (even if they were ZIP files) and When clicking on them (not in Redsn0w) it says they're INVALID or corrupted.
