Putting your life in your handset is risky, especially if you kill it. But at the 2009 MWC, i-mate showed off a handset that can take much more punishment than most.
Named after a US military spec, the 810-F can be dropped from three metres (10 feet), works in temperatures ranging from sub-zero to 60 degrees Celsius, is dustproof, and water resistant.
Dan put its toughness to the test by driving over it in a car. It stayed in one piece and even its touchscreen was still working.
If you prepared to splash out £600 on this handset when it comes out in April, then you too could impress your friends. One of its useful features is that your data can be protected if you lose it.
"If this device is lost or stolen, you can log in at any place and set a lock, an alarm, and even wipe the data located on the phone at any time," said Michael Cavey, sales director at i-mate. "And if it is damaged we'll replace it."
