No.
Edit: If you mean pirated apps, no, just transfer your purchases to iTunes
If you mean apps downloaded off cydia, yes they will be deleted.
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).
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)
If you jailbroke it by using cydia all the apps and cydia apps will get deleted
you cant anymore
Technically yes because it will remove your jailbreak if you update and any cydia apps, such as installous will be deleted.
you can update them by finding the newer version on the site you downloaded it from example : you have 1.0 you look for 1.20 or 1.5
Go to software update after plugging in itouch and tapping it's name. Then do software update. Most updates don't delete anything.
Free apps daily. You can get it in the app store
Hope this helps! 1. Hold your finger on the app you would like to delete (or any app, doesn't matter which one you hold it on.) 2. Next, your apps will start to shake and most of them will have delete buttons to delete them (on the top left of apps). 3. Click on the "X" and delete.
Unfortunately, you can't without jailbreaking it. If you have jailbroken it, just delete it like a normal app.
