With the coming April update, we will unfortunately have to end support for all Apple devices running on iOS versions lower than 5.1.1 due to technical reasons beyond our control.
In order to keep playing Clash of Clans, please update to the latest iOS version supported by your device as soon as possible (before the next Clash update). Without a supported iOS version you won't be able to play.
