can't get Snapchat back
I recently deleted the app Snapchat, but after trying to sync my apps to iTunes, and retrying to download it from my iPod 4th Generations with iOS 6.1.6, it still doesn't seem to work. I know that I don't have iOS 7, but i was able to download it before when it required iOS 7. Help?
iPod touch, iOS 6.1.6
