Yep, fell/flung/thrown off a dock with my Motorola W755 Razr flip-phone into lake some years ago - found it with my toes on the lake bed, had an incoming call and it was vibrating lol. In any case, fished it out (5 minute max immersion), pulled the battery, dried it out, and used it to the end of the contract. It's been retired but I can still fire it up even today.
Another underwater electronics story concerns an 83 Toyota pickup I had the misfortune of getting caught in a flood with (the authorities had to come get me out after the bed filled, knew I was in trouble then lol). Anyway... it was underwater for 2.5 hours and I just used a hose to wash it out after I got it home. Left to dry out for a month then got started cleaning it out - bonus to Toyota, they seal their components pretty good, only filtered water got into the engine/transmission - changed all fluids and started it up. Of course the starter only lasted a few more times due to crud inside, net loss was battery, radio (powered at time of flood), HVAC blower motor, and speakers. Drove it a few more years after that, occasionally would hit a hard bump and mud would fall out from under dash - made me smile.
Bottom line: electronics are pretty tough.
