I dropped my 3GS and cracked the screen. Fell about four feet onto tile floor in my house.
I was carrying it with a stack of laundry in my hand, the whole phone was unprotected. Now with my 4S, I'm terrified not to protect it. I have an Otterbox Commuter on my 4S right now, which I like, but am disappointed the case is too thick for me to plug it into the adapter in my car to listen to music, so I'm looking at other case options that will allow me to do this. I spend a good 30 minutes driving to work every morning and prefer to listen to music on my phone on the drive, so I was disappointed when I went to plug my phone in, only to find the Otterbox was too thick.
