I had a kickstand on three of my android phones. Useless appendage.
I'm not sure what everyone is whining about how a 4inch screen will make a phone unpocketable. You are talking half an inch of overall length and less than half an inch to width.
Most of the four inch screens I've seen make better use of the face of the phone (look at an android phone, you won't find much space on the front not taken by the screen). The iPhone on the other hand has swaths of space on the front, I would submit there is room for a four inch screen with out growing the phone into a brick.
