nah, atleast some of the models are unbreakable. My Nokia 6610 is not a special phone or anything, but it just won't break. It has been dropped to the floor about 40 (maybe?) times, thrown against a wall maybe like 5 times, once almost as hard as I can throw. And only damage that has happened from those is that a small piece of plastic came off. So it's still working fine. But then once it was in my pocket and I walked past a table and I think the phone hit the table and the screen broke. Well not the screen, just the plastic cover ontop of the screen, so I could fix it by replacing the cover but I haven't bothered.
My friend has got serebral pausie,and he drops his pnoe like 10 times a day and it is a nokia
