I've killed one phone while fishing and one while camping through damp.
I also got our digital camera quite smelly while using it to snap my fish at night much to my other halfs dismay.
The solution I've found is a water resistant mobile phone with a 2mp camera.
It's a Nokia 5500 sport and it really does the business.
The camera is pretty good and it's already proven it's worth on the first trip.
I was out fishing on the Shannon a few weeks back on the brothers boat, we did a day lure fishing for pike before the weather got too bad. ( one take, fish lost ).
I handed my jacket to my brother who was cold and said watch that there's a new mobile in the pocket.
A few minutes later my other brother pointed at the floor of the boat and asked if that was my phone sitting in 3 inches of bilge water.
Not a bother on the phone at all, still working fine, it sat in the water for at least a half hour.

That's it there, available with the yellow or silver trim, although I know O2 here only have it in silver.
Not traditional tackle I know but maybe others were looking for a waterproof camera/phone solution like I was.
