If you delete an app on your iPod touch, can you get it again for free?
Yes go to the app and make sure u r signed into ur apple account then look up the app and press and make sure before you download it it says install or else it will make u pay again. Another way is go to updates and press purchases then find the app
yes :) do it all the time
Yes. Instead of the button you would click to get it for 1$ or so it would say install instead.
Yeah, by going to purchases in your ipod or iTunes
