Does a otterbox really work?

I'm thinking about getting either a iPhone 4 or 4s. I tend to drop my phone sometimes & I was wondering does a otterbox really work? If I was to drop it would my screen crack(with the case on)? Just until I could get a life proof case.

Yeah i dropped mine off a roof and there wasn't a scratch in my phone!

Depends on which one you get. For the most part, the commuter series will protect the phone pretty well. The back, the sides, but not so much the screen. If your phone lands face first on pavement it may shatter the screen. If you get the defender series (the really big bulky one) it comes with the front protected too. You will most likely not break anything at all with the defender series as it covers the phone all the way around, even the screen.

  • Lifeproof iPhone case, does it really work? The lifeproof iPhone case claims to shock proof, water proof, sand proof, and snow proof. I'm interested in this case for the protection and for the water proof factor. So what I'm curious for opinions because I don't want to pay 80 $ for a phone case that won't work
  • IPhone auto brightness- how does it really work? Once I unlock my 4s, the screen either gets brighter or darker, depending on lighting. Now, let's say my screen adjusted itself to a brighter setting in a bright room. Without turning off my phone, I move to a darker room. Now shouldn't the brightness automatically dim? Or is this how the feature works (adjusts only when device is unlocked)?
  • IPhone 4s- What external battery will work with my Otterbox case? I have an iPhone 4s with the Otterbox Defender, and really need an external battery. Like the Mophie Juice Pack Reserve. I don't think that it will fit with my Otterbox, so does anybody have any ideas of what battery to get so I can continue to use my case?
  • I've lost my iphone 4, does the find my iphone app really work? I've lost my iphone 4 and it has the find my iphone app, i was wondering if the app really work? Even if the app is deleted from my iphone, can i still locate it?
