Almost any phone will NOT break if you take care of it.

People on my account have used Blackberries(last one was used for 3.5 years before upgrading), HTC TP2(used 2 years), Droid X(used 2 years), Thunderbolt(used 2 years), etc... All except for the BB are currently in working order. The BB trackball wore out from overuse after 3.5 years. ALL of my old basic phones are ALSO in working order. I normally loan/give them to friends who are not so careful with their phones.
