I've been with AT&T for a couple of years. My cdma phone worked good everywhere but Chatsworth.....
I recently traded up to the new 3G Iphone last week. It seems ok but the volume on the ring can't be adjusted loud enough to hear on a busy street by me. Also, it seems that I have to re-pair the bluetooth headset if I want to use it that day. Here, again, I might be missing somthing. The touch screen is nice. Overall, an 7/10 so far.
