So recently Youtube updated it’s app, and while I’m on ICS on my devices now, the update had a gem for those on Gingerbread (i.e. just about all of you not using a Nexus) — it allows your phone to view HD youtube videos if your device can handle it.
Can your device view HD? Because that’s a question… what is HD? Just about as ubiquitous a term as ‘digital’. Is 480p HD? It once was… 1080i… 1080p
Either way, grab the update and see if you can get HD with it.
