Can I listen to my iPhone in the shower with a lifeproof case?

Just got the iPhone 4 and purchased a case from this link that says its new. The seller has good reviews.

I'm pretty sure I heard that you can use your lifeproof case in the shower. Is that true? I wanna be 100% sure cause it doesn't have insurance.

I won't try it
