AT&T on Friday announced a new feature for its data plans called Stream Saver. The carrier calls it a "free and convenient, data-saving feature" that will cap most mobile video streams at DVD quality (or around 480p).
It sounds harmless at first, but customers who aren't concerned with data may not like that the feature will be enabled by default. To watch hi-def video, you'll have to opt out via the myAT&T app or the AT&T website.
