If you're feeling 'stupid and contagious' you may just do something silly with your iPhone. Like use it as bait to catch a naked swimming baby.
More likely you'll just drop it in a muddy puddle, or on the pavement, or be fooled by a recent (and obviously very false) claim that updating to ios7 would make your iPhone waterproof!
Nevermind. Protect yourself with the Nirvana of smartphone protection - the Lifeproof for iPhone5.
Take your time, hurry up. The choice is yours, don't be late! Buy one today.
