exactly what the title says. with my old 3GS, when i used to slip it into my pocket and pull it out, the screen would usually just clean it self pretty well by rubbing up against my pocket. i can't say the same for the iP4. it always looks smudged all over the screen, even after pulling it out of my pocket. also, cleaning it with a micro fiber cloth takes more effort than it did with the 3GS. any others noticed this?
