no, updating your ipod will update games and bugs on your ipod but leave music
Now you will not delete all your apps. If you restore your ipod it will delete all your apps but you can always re-download for free, even if it cost $ before. (Don't update if you have a jailbroken ipod)
delete the songs you want off your ipod off your itunes library. plug your ipod back in and it will update.
you can delete the actual game but im pretty sure you can delete the actual update if that helps
no it will not delete it by itself but to download things that are new onto tour iPod then you are going to have to delete it or start downloading things on your iPod with your old computer again.
YES IT DOES. I HIGHLY RECCOMEND YOU TO NOT UPDATE YOUR IPOD OR IOS DEVICE, WHATEVER IT IS. I have the oldest version of the apple Ipod and i wanted to update it to 4.0 update and it said if i was to do that, then i would lose EVERYTHING.
To delete updates on your Ipod, you will need to move all of the music onto your computer and then manually reset the Ipod back to factory settings. When you hook the Ipod back up to the computer, do not update it and just add the music back.
after a certain amount of time your Ipod will require a resync to update license, if you delete the songs you may need to repurchase them. I am not entirely sure but if you change the settings on your ipod so that you update it manually rather than syncing it you might be able to delete them. well first sync it once then change your itunes setting so that it doesn't automatically sync songs when you connect your ipod then delete your songs of your computer
delete them from your itunes libaray then update your ipod.
iPod Touch software updates should not and do not delete everything.
Technically yes because it will remove your jailbreak if you update and any cydia apps, such as installous will be deleted.
No. If you sync your iPod it wont delete your apps. But if you click "Restore" while the iPod is plugged in, then it will restore you iPod to how it was when you bought it (no apps, no contacts, etc.) and then update it to the newest version of software.
