Hmmm I'm wondering if mine is from the cold or it's just screwy. It seems when I'm trying to dail in phone mode, the number 3and 6 sometimes won't operate. All the other numbers type when I type it. It takes a few seconds before I can type 3 and 6. The phone is usually in my coat's pocket. I make my calls in the car, not outside. This was with temps in the low 30's. Weird thing is, when the temps were in the low teens, the phone worked fine. I just find it odd the phone works at a lower temp but sometimes won't at 32F or above.
