The past few months we’ve seen official apps slowly trickle into the Windows Phone Store. And for those services (cough YouTube, cough Instagram) that don’t provide an official app, third party developers have stepped in to provide incredible applications.
Sometimes doing a job so good it’s hard to see what companies can do better (Metrotube is a great example of this). Unfortunately, most apps require workarounds to function properly and can easily be broken by a change server side to all these apps. Right now users might experience some issues with MetroTalk and GVoice because of some authentication issues.
