WhatsApp has a fairly major update released today. The biggest change is the UI, which is completely overhauled and definitely iOS 7 friendly. broadcast lists: communicate with your classmates, work colleagues or just friends by messaging many people at once. improved share location: 3D map view, hide places, search places large thumbs: see more new notification alerts and sounds: WhatsApp Settings > Notifications > New Message. application will now use your device text size as configured in iOS Settings > General > Text Size new improved User Interface for managing your blocked contacts: WhatsApp Settings > Chat Settings > Blocked crop image before sending Not sure why, but I'm seeing duplicate contacts in my favorites. These appear to be auto-generated from my contact list somehow as I never set 'Favorites'. Weird, they updated the app, but the screenshots still show the old iOS 6 app in the App Store. There's also a nifty new iOS 7 looking icon. All in all, looks to pretty nice. I'm not a big user of Whatsapp, so can't comment on whether it has any significant advantages to the old version. Any Whatsapp users? Why are you using it instead of iMessage or SMS?
