Joe Belfiore was on a teasing and tweeting spree last week about new major apps coming and we saw Pandora, United Airlines and updated Skype making their way to Windows Phone store. Now, he says even this week may see some major apps getting published, but doesn’t want to reveal the dates. Better news is that unlike Pandora and United Airlines which are US-only apps, this week will see major apps more global in nature. This brings to our attention that Viber may be one of the candidates. Let us see what happens next…. Stay tuned.
