iPod touch ipod touch jailbreak questions

i wanted to jailbreak my iphone 4s but found out i cant because its 6.1.3. so i thought id jailbreak my ipod touch 4th gen, but found out it too is up to date! so do i have to wait till the new version comes out to upgrade then jailbreak?? and if i can jailbreak it now i was wondering how i go about downloading new music. i use a youtube to mp3 thing then put it on itunes, but i thought u cant plug it into itunes when its jailbroken? and i want to keep putting new music on it. any help is greatly appreciated!!!
