I'm getting an iPhone 4S in about a month, and I want a case that will protect it from, water, sand at the beach, & you know, stuff like that. I've looked into two cases: Lifeproof ($79.99), and the Otterbox Defender Series case. Although the Lifeproof is expensive, I really like how it's waterproof, shockproof, dirt-proof, etc… The Otterbox Defender seems to be a good choice as well for its good reviews. I've looked into these two cases very thoroughly, but I can't make a decision. So can you give me some first-hand opinions of each case, like pros and cons, and how well the cases worked if you own them? Or even recommend a different, better case to protect my iPhone from everyday life?
