Nokia's not exactly known for its beefy, ultra-survivable gear, but unless the human race plans on getting a whole lot less clumsy, rugged phones will always be a good idea -- and Espoo's 3720 certainly seems to fill the bill. The Series 40-based candybar features a 2 megapixel cam with LED flash, triband EDGE (sorry, North Americans), FM radio, microSD expansion, and the latest and greatest Bluetooth 2.1, but the real news here is that the phone is built to meet IP54 standards. A quick check with our handy-dandy IP code reference tells us that means that "ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact" -- in other words, your phone might get nasty dirty, but it'll keep chugging -- and it can withstand "splashing" water. Scuba divers, the search for your perfect phone probably continues. Refreshingly, the 3720 will run just €125 (about $175) unlocked when it ships later this summer.
