Hello, My boy has an ipod 4, on 6.1.6 and he deleted his instagram app. I've attempted to reinstall it from itunes (doesn't work), and also to download it directly onto the device using the appstore app. When I attempt to do that, it says he needs to update to ios 7.0 in order to download the app. I was under the impression that there was a way to download the app if your software version was unable to updated any higher (he is at the highest software update offered by apple). Any suggestions on how to get this to work? Appreciate the info.
