Oh that is the dock... it changes with the software update on iTunes. Just connect your iPod on iTunes and update! This next part is ONLY if your device is jailborken...if your iPod is currently jailbroken then you may not want to update because the jailbreak will be lost. But you can re-jailbreak with Limera1n.
