Hey, I just downloaded WhatsApp Messenger on my Android. It is a Smartphone Messenger which replaces SMS. This app even lets me send pictures, video and other multi-media! WhatsApp Messenger is available for Android, iPhone, Nokia and BlackBerry and there is no PIN or username to remember – it works just like SMS and uses your internet data plan. Get it now from http://www.whatsapp.com/download/ and say good-bye to SMS.
