I've found an app that allows to force rotate any application, including the Touchwiz launcher and several video streaming apps that insisted to work in landscape mode only counterclockwise.

Now I can operate my Note even upside-down. Why, you ask? Well, in an Iphon-esque way, the antenna is on the bottom side, near the buttons, and when I'm in an area with low signal, my hand interferes with it and 3g stops working. When upside-down antenna goes far from hand and data flow gets unhindered and faster!
