Your opinion: Best protective case for an iPhone?

It seems the Otterbox is the most go-to brand but does a Griffin case do just as well? What other brands work? I'm new to the iPhone world and I don't really want to drop and damage an expensive phone.

My iPhone 4S is slow to go back to home screen?

Hi guys… My iPhone 4S is fairly new. Got it a few months back. When I'm in an app and go back to the homescreen it seems slow. I even compared it to my moms iPhone 4S and my sisters 4. Also when it's in sleep and I hit the home button, it's slower to come up than my mom and my sisters iPhones. I don't have a lot of apps and not very many pictures. Is this something I need to really worry about… Do you think I have a faulty 4s

How much to sell a white iPhone 4 for?

I recently bought an iPhone 4 from a friend for 140$ I didn't realize it was with Verizon so I'm trying to sell it and buy one that's with AT&T, but not through AT&T. The iPhone is white, 8 GB, and has a cracked screen. I don't know whether to sell it for the same amount because I was looking online and they're being sold for a lot more than 140$. How much should I charge, because I have two people looking into buying it, they just need to know a price.
