Google has launched a new and vastly improved mobile web site for YouTube. The new version uses HTML5 to offer high quality video streams as well as an improved user interface that’s easier to navigate on a device with a touchscreen display and HTML5 capable web browser (which includes most Apple and Android mobile phones).
You can find the new page at m.youtube.com.
While there are already native YouTube apps for Android and iOS, only the Android version supports high quality video streams. That means if you want to stream video in higher quality on an iPhone 4 with its extraordinarily high resolution display, you’re probably better off using the web version than the native app.
The improved site navigation also makes finding videos, subscribing to channels, and performing other activities faster, thanks to new touch-friendly navigation features, as demonstrated in the video above.
