My nephew dropped my mother's cell phone in the dog's water dish once. A friend of mine, his 4 year old son tried to flush his down the toilet. Both phones recovered with dry out time. Give it a couple days and it may recover itself (I do agree with trying some sort of drying agent in a closed container). Good luck.
By the way, it's usually Hubby who has to convince the wife. Never heard of it being the other way around
.. Since it's not my money we're spending here, my vote is for the K7 if you have to replace.
