You spent a lot of buckaroos on your trusty iPhone ( or Blackberry ), so do yourself a favor, and protect it.
This Otter Box Defender case is ideal. It’s tough, has it’s own screen protector, and covers for those vulnerable holes ( for headphones, charging ). If you travel a lot, you need this. There’s another version without the belt clip / holder, and it costs about half as much. Get it on Ebay for best price.
Otter Box makes cases for other gadgets too. Check out their website
