The specs say differently:
Operating temperature: 32 to 95 F
(0 to 35 C)
Nonoperating temperature: -4 to 113 F
(-20 to 45 C)
Relative humidity: 5% to 95% noncondensing
Maximum operating altitude: 10,000 feet (3000 m)
You have got to be kidding me!!!
*Minimum* operating temp of 32 F?!?!?!
How the F can they sell this phone in northern climates? I live in WI and in Feb I will frequently go outside on a nice day to take a conf call and get some fresh air. A nice day being, at least, in the upper 20's.
Seriously dude, WTF?
A complex system that works is invariably found to have evolved from a simple system that works.
