Hey,
I used an old Audiovox "candy bay" type phone for many years and found it to be very tough even though it was not rated as such. It got wet on many occassions and once ended up in the lake but I would just take it apart, dry it with a hairdryer and put it back together, no problem. It was dropped 1000's of times in the 6 years I carried it; eventually the #9 key would not work and my co-worker became frustrated with it and pounded it into the dashboard of the truck, cracking the display screen and ending its life.
I searched the internet and wanted to purchase a Motorola
i-580 but they would not function in Northern Ontario so I ended up buying a Sanyo 7050, it is mil-spec rated for shock/dust/vib. but not for water. This phone seems tough but I am not impressed with the sound quality.
Mike
