I just dropped my iPhone for the first time today onto a wooden floor. After checking it, I noticed some cracks forming near my volume switch and silence switch (although, I doubt those are from the drop). I scuffed up the sim card tray a little bit and I noticed it was dirty so I pulled it out and began wiping the dirt and dust away from it... while I was doing that, I blew into the open hole (bad idea) and now I have dust inside my glass that I can't seem to get rid of. What a crappy day... hehe. I'm glad my screen didn't crack though.
