SparOne and PowerSkin have come out with an emergency-specific, screen-less GSM dual-band cell phone that is the only one of its kind to run of off just a single AA battery that is said to last a mind bending 15 years. You'll never have to worry about recharging this phone making it perfect as an emergency backup phone to have around. Of course that is if you never use it. Talk time with the included Energizer Ultimate Lithium AA battery is 10 hours. TheSparOne uses MicroSIM and comes with one already inside and will be available early this year for $49.99 without contract.
