Re: So you just dumped your cell phone, Iphone, small camera in the drink ....
In the West (Denver and beyond) it is very arid. Open up the phone and all orifices that may be closed, remove the battery, and balance the phone on top of a small surface like a medicine bottle cap. Just let dry. The air typically has very low humidity (except during rain storms). Things dry out very well and quickly.
Although it's humid along the coast, I live 20 miles inland from the Pacific Ocean, and I might as well be in the Mohave Desert it's so arid here.
