I have an 8GB iPod Touch 4 on iOS 4.3.5 I play a lot of MineCraft PE and Clash of Clans on it and it generally runs fine, until today. Clash of Clans has a new update which requires iOS 5.1.1 so the game will not start. It will start loading and then a message comes up saying there is a new version and it takes me to the App Store update. When I run the update it comes up withe the message saying I need 5.1.1 Is it worthwhile upgrading to 6.1.6 so I can continue playing Clash of Clans? Basically I have lost my village as I can not load the game anymore. It don't really do much except play games on it. What issues are there with the iPod Touch 4 and iOS 6.1.6?
