What otterbox series is the best for defending your iPhone? - 1

I'm looking for a case that will defend it from dents and cracks and scratches

There's the Otterbox Defender or Communter (the communter is thinner and doesn't have the front protection the Defender has), or there's a Lifeproof case. The Lifeproof is made to protect from everything, including water damage, but they're around $80. The Defender will run you about $50 and the Commuter about $35.

There are so many iphone cases here, you can choose whichever you like, http://www.onecase.co.uk/iphone-cases.html
