A:AnswerYes the device does have the classic Apple Messenger app. You'll want to make sure the device has a Wi-Fi Internet connection to use it though.
A:AnswerI think you can. Past versions of the iPod touch you were able to do that. I have a 2nd generation iPod touch and i had done that but i didn't try it with this one because i don't use it much on the iPod touch.
A:AnswerI am fairly certain it was running at least 13, when I bought it about a month ago. I upgraded quickly after getting it, and running 14.6 now. iOS 13 would be a little out of date at this point.
