One of the most popular social media messaging application WhatsApp has stopped working in older iPhones and Android handsets to ensure that it could continue to introduce new features and stay secure, which relies on the app being used on newer operating systems.
Anyone using Android 2.1 or 2.2, an iPhone 3GS or iOS 6 will find the app has stopped working. The same will happen to anyone on Windows Phone 7, the Independent reported yesterday.
The company has advised that anyone with one of those older handsets who want to keep chatting with friends simply has to buy a newer phone.
WhatsApp had initially said that all BlackBerry models and some Nokia handsets would also find themselves unable to get onto the chat app. But it went back late last year, apparently in response to complaints.
