WhatsApp to cut off support for millions of phones, tells people to buy new ones instead

WhatsApp is about to stop working on millions of phones. Older devices are going to have their support cut off so that they'll no longer be able to use the free chat app. Phones including the iPhone 3GS and Android handsets are about to stop being supported by WhatsApp's engineers. And when that happens, owners will no longer be able to send or receive messages. WhatsApp first announced the change early this year.
