That's funny, -- 2 articles about BlackBerries being dropped in water, in a short period. Here's a success story posted here
You may have good chances if you reacted quickly and kept the battery away from the BlackBerry (always resist the temptation to test the BlackBerry, always keep the battery removed). The BlackBerry has survived "in statis" (wet) in non-corrosive liquid for several hours, as long as the battery was kept removed or that the battery was dead during this time.
Disassembly was the correct procedure. But keep it fully disassembled now. Don't reassembled the BlackBerry or test the BlackBerry until:
One of the below:
(1) 1 week of unassisted drying on disassembled components; OR
(2) A few days of direct sunlight or under an incandescent desk lamp (3 days worth) for the disassembled components; OR
(3) A few hours of low-temperature oven bake at 150-180 degrees F. Always BELOW boiling point, use a thermometer (motherboard only, no screen -- the screen should still be dried out too though, so put the screen in direct sunlight or lamp while you bake the motherboard)
I use approach 3 because it is the safer method because it gives water less time to "rust" the BlackBerry circuitry. Remove the screen too (it's held down by just a couple screws and a snap-off connector, be careful with it), since water can go under the screen.
Don't forget to read the instructions first
, as well as my other post
. It is important that correct procedure is followed (most particularly quick action for maximal chances, and odds are usually improved if you remove battery ASAP and resist the temptation to test the device)
You may want to use the distilled water rinse method that I used (motherboard only, no screen), if the lake water was dirty or the BlackBerry fell into mud at the bottom of the water.
Please remember your odds are reduced somewhat if you did not remove the battery immediately, or you succumbed to the temptation to test the BlackBerry with the battery. (Water+power = short circuit = instant damage .... Must dry 100% first before testing!) Sometimes the battery short-circuits itself before it manages to short-circuit the BlackBerry, so try testing a different battery too. (You got lucky if this happened, better a new battery than a new BlackBerry)
