The Blackberry messenger killer app has come to Windows Phone 7 too.
Blackberry messenger is one of the most beloved things for Middle East mobile users, but WhatsApp is the app that brings Blackberry messenger like instant messaging facility to other platforms. The beauty of this app is that it allows cross-platform messaging and since it is linked to your mobile number rather than a web based login / password system so SMS can go without any SMS rates being applied to you. And the good news is that WhatsApp is finally available for Windows Phone 7 users too, making it a truly cross-platform app.
Available in the Windows Phone market place now, this app works just like it would on iPhone or Android and allows you to chat with your friends without worrying which phone they are using. Although some users have reported that WhatsApp currently doesn’t work with their WP7. This is because the app is mainly designed to be used with Mango version of WP7. So, if your current WP7 handset is not working with this app, just wait for the Mango update to be released soon and you can join the WhatsApp community to fulfil your social messaging needs.
