I've jailbroken my iPod Touch 4g and it hasn't really slowed down. The only downside i think is that the boot-up is a bit slower than usual. But otherwise it still runs fast :-)

well i never really turn off my ipod, always put in sleep mode.

I woildnt cause you could break it :arrow:

i wouldnt break it, i know how to do, but im just a little worried, and so is my dad.

i jailbroke my 4g.. its reallly not worth it, its not all that once you get it jailbroken. and it also voids the warranty, wich means if it messes up u cant take it back.. but if you do jailbreak it, use limerain

i say don't. itll make it slow and itll die faster.

i wouldnt do it i got the ipod touch 4th weel it came out and i didnt jail break it... this is what i suggest doing using frost wire for your songs and just paying for apps with itunes cards

I Jailbroke my Ipod Touch 4g and IPhone 4g and neither of them are slow they take about 7 secs to respring so im not sure what you guys are talking about and you could always over-clock it with the jailbreak to make it faster....
