Viber's free mobile application for the iPhone, iPod touch and iPad was updated earlier today in the App Store with four new features. Bumping the version number to 5.6, the new Viber for iOS lets you express yourself in a more detailed manner than before with support for 7,000 characters long text messages.
In addition, you can now like messages in group chats, forward the contents of public chats and take advantage of better video messaging features that improve your experience.
