The Russian website mforum.ru has done a rather astonishing durability test of the Nokia 5500, and it did rather well. They put the 5500 in a vacuum cleaner, buried it in a garden, bathed it in milk, bathed it in beer, held it under a tap, dropped it from a height of 2 metres, then 4 metres, then 6 metres, and finally ran it over with a car. It survived the lot, and only broke when they ran it over with the car a second time. The site's in Russian but the pictures and videos speak for themselves.

You can get a rough translation of the page by going to Alta Vista Babel Fish  and inserting the URL of the durability test page ( http://www.mforum.ru/phones/tests/036591.htm ).
