When I travel, I always pack a zip lock back full of rice...it's a strong natural dessicant and can help dry out sensitive electronics, restoring their functionality. I have used it to successfully bring back to life a cell phone that fell in a tub, a (high $$) digital camera that got stuck in the rain, and a laptop keyboard that I spilled water on. High sugar liquids (i.e. soda, wine, etc.) will probably damage circuitry irreperably, but for just water, melted snow and vapor exposure, packing the item in white rice overnight has saved me lots of heartache and expense.
Not sure how well it works with cod digestive juices.
Thanks for the tip. Wife unit and I bought two cheap late model unlocked blackberries just for travel. (I’ll sometimes join her on her business trips and be touring while she is in meetings.) We’ll pop in a local SIM chip of the lowest denomination and communicate mostly by text. If we lost one of these it would be no big deal.
