How do I jailbreak my ipod 4g ios 6.1.3?
The first step in jail breaking the iPod is to download the Redsnow program. Run Redsnow, click on extras then "select IPSW" Direct Redsnow to 6.0 IPSW to identify the firmware. Click the jailbreak button and enter the Device Firmware Update mode. Visit http://www.evasionjailbreak.com/jailbreak-6.1.3-semi-untethered-ios-on-iphone-4-3gs-ipod-touch-4g/ for more information.
I don't know what to tell you,but if you look up on Youtube there is plenty of videos on how to jai break your device.(Just make sure it's the same software version that you have or else it won't work).
