Hence why all my family members who work in construction have very cheap Nokia phones. The problem is solved.

They work in crappy environments, cost $20 to replace (my father in law has 5 of the things in his truck) and last days on a battery. They also tend to still work if you drop them lots.

Also, technology doesn't really help construction that much really unless it's on a large scale (which actually makes up a very small proportion of actual work done).
