Technically yes because it will remove your jailbreak if you update and any cydia apps, such as installous will be deleted.
no, updating your ipod will update games and bugs on your ipod but leave music
yes
You go onto installous or whatever you have and down the bottom there should be a sign saying updates. You click on the game you want to update and install it. Delete the old version.
The iPod Touch should not delete things when you update it. All content should remain on the iPod (unless you have a jailbroken iPod, in which case it will remove all non-App Store apps and other jailbroken features).
No it does not. All apps from installous are free but you will not be able to sync the apps into itunes. you will not be able to sync unless you delete the apps. If you get appsync from cydia you can sync apps without deleting.
Try installous or cydia, not on appstore
iPod Touch software updates should not and do not delete everything.
Every Thing!!! just Jailbrake and install Installous!!!
You do not pay to update your iPod Touch unless the software update is to 3.0 or 3.1.
Downgrading your iPod Touch should not delete anything.
Connect your iPod touch to your computer. Go to iTunes and click on your iPod touch, then click Update.
Go to installous, ang go to settings
