Is it possible to download and install the old snapchat app on older model apple devices to view the top 3 or top 5 best friends or whatever they had? I already have a jailbroken device on IOS 8.x and just wanted to know if this is possible. I also have an old ipod touch on a much older ios firmware and if I get the IPA for the older version snapchat would it work? If not why?
