WhatsApp Web was launched back in January, and it worked well with Android and even Windows Phone but the support for iOS has been lacking, atleast till now. WhatsApp Web now works with the app on your iPhone.
In order to use the Web Interface you have to go to the "WhatsApp Web" option in Settings menu of the iOS app on your iPhone. Then head over to web.whatsapp.com on your PC, and scan the QR code given there with your iPhone.
The update is being rolled out in a staged manner, so it might take a little time before its available to everyone.
