WhatsApp Messenger is now officially available on Android Market and it is FREE for the first year. As comparison, Blackberry users pay US$1.99/year with 90 days free trial while iPhone users pay a one time US$0.99. Nokia users however are also paying US$1.99/year but they similarly get to enjoy it free for the first year as well. So it is quite likely Android users will pay $1.99 after that.
So what are you waiting for? You can search it up on the Market or download via AppBrain here.
