Facebook-ownedWhatsApp, the world’s most popular mobile messaging service, has received a nice little update Monday bringing some much-needed privacy controls.

The same privacy settings are available for your Last Seen status as well – useful when you don’t want others to tell you haven’t opened their messages yet. Oh, and this edition of WhatsApp also includes some nice new wallpapers.

WhatsApp version 2.11.8 also includes – you guessed right – bug fixes.

If the supposedlyleaked screenshotsof a forthcoming WhatsApp update are an indication, the company is now testing a voice calling service itpreviously said would arrive by this summer.

And if you’re jailbroken, there’s a newjailbreak tweakout, calledWhatsApp Unlimited Media, thatremoves WhatsApp’s annoying restrictionwhich limits your photo sharing to only ten photos at once.

Download WhatsApp in the App Store.

The app runs natively on the iPhone and iPod touch and thanks to a recent update it now plays nice with iOS 4.3 or later. As a reminder, WhatsApp is free for the first year. After that, it’s a $0.99 a year play.
