See if you can find the Nokia 6015i. My job is also phone-hazardous, and my nokia has survived a 40ft drop, as well as countless fumbles and being crushed in my pocket worst that happens when you drop it is the faceplate and battery fall off, but that's about 30 seconds before you're up and running again. Verizon won't carry this phone anymore, but you can pick one up on ebay for ~$20. I'd advise against flip phones if possible, i've made that mistake before, and was changing out the phone once a month. Hope that helps!
