Mobile Phones and DSLR cameras in winter?

I come from a tropical country and about to make my very first winter trip to Harbin. I know temperatures in Harbin can drop to -20 Farenheit (-30 Celcius).Is it okay for my phone (Galaxy S3/Blackberry) and Nikon DSLR camera to be exposed to such cold temperatures? Will the cold temperature damage my electronics? I heard from other people that their DSLR camera's battery life is drastically shortened, is this true? What about my phone's battery life?

I will very much appreciate if you guys can give me precautions for electronics in winter, thanks in advance!

Long Exposure for a Nikon Coolpix 510?

I've been messing around with my new coolpix camera and have finally gotten a handle on the Manual, Appeture, and Shutter settings. However, I can never set the timing for more than about eight second. I was hoping to use my new Tri -pod you capture long exposure photos such as star trails. How would I set my camera to capture a picture for about an hour or more? Is that even possible with the coolpix? If not what would be a camera to save for? Thank for the help!
