Look at the new Samsung Rugby handset sold by At&t. Currently it is the only rugged handset sold by At&t. Might suit your needs, not sure it meets all your requested features but worth looking into.
My cell phone has become an electronic swiss army knife that I use daily in my construction job. I need a sturdy unit that would do the following:
Good reception on ATT system
Vibrating ring option
Music/FM radio would be nice
Able to withstand rigors of a job site.
I trashed a Sony Ericsson w850i & my Nokia 3200 is wearing out and has few of the above features. I've been perusing the internet for too many hours with little luck.
