YouTube v4.0.8E with 720p HD playback (WiFi + 3G)
Requirements: Android 3.2+ (HC/ICS/JB)
Overview: The latest version of the official YouTube app.

[break]
Keep up with your favorite YouTube channels and access the world’s videos anywhere with the official YouTube app for Android.
I saw some threads floating around about youtube 720p playback, and I really always wanted that too for a long time.
But I was stupid enough not to even try it.
I did try now and, yep, I got it working!

How I installed it:
• Removed /system/app/YouTube.apk (you need a rooted device for this step! If your device is not rooted, try ignoring this step, but installation may not possible.)
• If YouTube is still there, just go into its app info tab and tap "Remove installed updates" or something, then "Force stop".
• Install my APK!
• Of course, your device must be capable of 720p video decoding!
