I needed a new one, because the other one was always turning off in the middle of dialing/talking/whatever. No, it wasn't the battery, because the battery I had for it was pretty new, had only been charged a couple of times. It was the phone. When the battery was brand spanking new, it still did that.
Same phone number.
Guess I'll start carrying my phone around now... my mom wanted me to do that so she could get ahold of me when I wasn't home.
I generally used the phone for emergencies, but it wouldn't be good to have the phone keep turning off if I was calling 911 for some reason.
