Desire a quick way to share videos easily online? Nokia is planning to release an app for Lumia Windows Phones, aptly titled YouTube Uploader. I don't believe there's much we can say about an app with such limited functionality, except you will be able to upload videos to YouTube. Unfortunately, while the app is listed on the store, you can't yet download it (even on a Lumia 925 with the GDR2 Amber update).
The app (according to the store description) will enable users to share videos easily by simply selecting the videos and uploading them. You're also able to use the Nokia Video Trimmer to edit the footage before choosing to share with friends. YouTube Upload can utilise both WiFi and data connectivity, so be sure to be correctly configured before uploading.
You will be able to download YouTube Upload from the Windows Phone Store, but just not yet.
