Why does my iPod keep crashing?
I've got a 16GB iPod Touch 4th generation, version 6.1.6, fully updated. It's just over a year old and I always take good care of it, and the storage isn't even half full. But over the past 2-3 days, literally ALL of my apps keep crashing when I go to them. Facebook doesn't even load at all, YouTube loads but crashes as soon as I tap on a video, Tumblr and Instagram and Vine and most other apps only work for a few seconds/5 minutes, iTunes and the App Store don't load, Music is sluggish and often crashes in the middle of a song, Twitter loads but crashes as soon as I try to view a picture or tweet anything or switch accounts, and Safari loads for a few seconds then crashes. I've tried closing them by opening the Multitasking thing and pressing the "-" button over the apps, I've tried deleting and reinstalling some of them, but nothing has worked. What's happening?
