Iphone 5 splashed with water?

My iPhone 5 was in a leather case and in my pocket and i got a bucked of water thrown at me and it socked straight through my pocket and when i pulled my phone out the case was wet, and i think the phone itself was a little wet too, i dried it off and turned it off for the night, the next morning i turned it on and everything seems to be working fine. Is it possible that it will still stop working, or do iPhones need to be submerged to really have water damage?
