Some phones are designed with an eye for fashion, others for functionality. I think you know where the Sonim XP5300 Force 3G is pitched.It's a follow-up to the Sonim Force XP3300, which we reviewed pretty favourably back in May. Performance, ease of use and battery life were all rated, not so features and the look and feel. But like we said, it's not up for winning any beauty contests.Where the Sonim 'tough' phones come into their own is being able to withstand pretty much anything thrown at them. the Sonim XP5300 Force 3G is no exception. It can deal with an hour in up to 2 metres of water, can survive a 2-metre drop onto concrete and has a Corning Gorilla galss screen that can withstand both shock and scratches. In short, it'll out-survive most phones on the building site or in the wilds. It's even got spaced key for using your phone with gloves. Yes, all bases covered here.The headline act for this latest model is the addition of 3G connectivity, with other features including a 2-inch high-resolution display, a GPS, a 2-megapixel camera with LED flash and video recording, an LED torch light, media player, FM radio, a microSD slot (able to take cards up to 16GB) and Opera Mini for web browsing. Still a strong battery life too, 22 hours of talk time and up to 1,500 hours of standby.No, it isn't an iPhone or a Galaxy S II, but it doesn't pretend to be. This is a phone for relying on when the going - and the conditions - get tough. If that's the kind of phone you need in your life, you can find out how to get the Sonim XP5300 Force 3G from the Sonim website.
