Nokia TV app is live and ready for Lumia devices, but it only offers Finnish content
For those who aren’t familiar with the app, it allows users to stream television shows through Wi-Fi or cellular connectivity. Currently though, the content provided by the app only contains Finnish programming. So unless you’re fluent with the Finnish language, it won’t be a useful thing to check out. Another cool thing about the app, is its ability to actually save television shows locally onto a device, so that it can be viewed offline at a later time when it's convenient.
