IPhone 5 case - LifeProof or Otterbox?

So, I need to buy one of them because I just got my new iphone 5 and will probably drop it 100 times. From what I see, the LifeProof is $79.99, is rubber, thinner than Otterbox and waterproof. Otterbox is hard plastic and $59.99. Not sure I want the extra bulk of Otterbox instead of thinner LifeProof. Anyone use either of these? Are there any more pros or cons to each? I read for LifeProof it can be difficult to use the touchscreen, is that true? Also, I bought one of the privacy screens, you know, where its tinted and unless your looking almost straight on you can't see anything on it, well, can I still use that? Also, I'm not worried about dropping the phone in water so do I really need the waterproof? Is it better for rain? Thank you for all help from anyone who has used either or both of these!

How to tell if my iPhone is unlocked

It's an iPhone 4s. My friend said he unlocked it and jailbroke it for me but how can I make sure it is?
There's a folder with 4 apps in it "Cydia" "unlockit.co.nz" "FuriousMod4s" and "Winterboard"…
I'm trying to activate it with straight talk and it's a sprint phone that's why I wanna know!
