As of March 7th, will be dropping support for players on iOS 3 / 4 devices. At that time, players on such devices will need to upgrade their device operating system (where possible), use another device, or play using the PC version. iOS 3 / 4 came out in 2009 / 2010, making them 7 and 6 years old respectively. Players on iOS 5 / 6 will continue to be able to play, however, they will be unable to get future updates to Kingdoms at War which will require iOS 7 moving forward.
