You can't,unless you have Cydia.
unless you had made a backup copy of that version you want to downgrade, you cant
Yes, you can. Go to jailbreakme.com on your ipod touch and you can directly jailbreak your iPod Touch from your iPod.WARNING: Make sure your ios version of your iPod Touch is 4.2.1 or lower or it will not work.
try to search it on google.com or just download apple itunes version 7.0 or lower and when you connect your ipod it will show "THERE IS A NEWER VERSION FOR YOUR IPOD WOULD YOU LIKE TO UPDATE''!!!
The iPod Nano version 1.0.4 is just an upgrade version of the iPod software, and just fixes minor bugs that have occured in the earlier software.
iPod software is updated by plugging the iPod into the computer and using Apple iTunes software to upgrade.
Well, depends on how new the "Ipod Classic" is.. If it is new, the 2008 models, it is just a new version of the ipod video. If it is a older version its a ipod minus the ability to playback video.
You can do two things: You need to turn on "sync only selected items" and uncheck what you don't want on the iPod OR Find a smaller version or recapture those songs (at a lower data rate) to increase the number of songs you can put on the iPod.
thats the ipod touch 4g
If you can't access apps on the iPod Touch, then you should try updating the software version of your iPod Touch to the latest version.
I could be affected by the version of iTunes u are using, check that ur ipod version is within the same sync catergory as the itunes version. if they aren't you may need to update the itunes version or get a new ipod.
no because the ipod touch 4 is a newer version
Yes the ipod or iphone will but not any other ipod.
