WhatsApp has finally arrived on the web, but unfortunately not everyone will be able to use the service.

WhatsApp Web, which promises to "mirror conversations and message from your mobile device," is available for Android, BlackBerry, and Windows Phone, but iPhone users are out of luck due to limitations in iOS as described by company.

The company’s desktop solution, however, is somewhat convoluted. To use it, you have to open https://web.whatsapp.com in Google Chrome and scan the QR code inside your WhatsApp smartphone app. Then, you must keep your phone connected to the Internet and make sure you have the latest version of WhatsApp.
