WhatsApp made its first big debut a few weeks ago and while the app is still missing a bunch of features, over all it works quite well on Windows Phone (nicer looking than the BlackBerry app at least).
Well, the other shoe has dropped as it looks like WhatsApp will charge for their services. Cost? A paltry $1.99 per year with the first year free. Now, before we all get in a hub-bub, this just makes the Windows Phone app on par with the other platforms (we know the BlackBerry version charges the exact same). And lets face it, if you're using the app regularly $2 a year won't kill you.
Still, consider yourself warned. You have 12 months to get save up for the big day. Thanks, Aljoša, for the tip
