Well, when I was working at them in drilling, a buddy of mine suggested the Cat S60 (which was not yet released) as I was in the market to upgrade from a Samsung Galaxy 5
It marketed as a "military grade work phone"
Just a heads up, this phone is horrible. 7 months in, and little to no abuse and it's almost useless.
The charging port broke after 4 months, so it's no longer waterproof. The screen locks for no reason. Images burn into the screen. You have to use speakerphone because it will automatically mute anyone if you touch the screen(even with facial hair).
The camera sucks donkey *****. It halos objects and has weird colour saturation.
For $899 I'd expect much better.
On the plus side, the screen is hard to break(I threw it against the wall outta frustration)
Anyhow, just a heads up. This phone is horrible
