Ok, I'm on Verizon, and so far GREAT service everywhere Ive been in Pennsylvania. Ive noticed something though. I live in a 2 story house so I'm not sure if that matters, but here's what I have deducted. The antenna MUST be at the bottom of the phone pointing down, am I correct? And if so, why is the Tour made this way, I know some other phones are like this as well.
When I'm in the living room, 1st floor, I usually have 3 to 4 bars. Fluctuating from 2 to 4, but almost always at 3 at the least. Now, when I hold the phone upside-down, it goes to 4 or a full 5 bars.
That's why I'm assuming the antenna must be at the bottom.
Upstairs on the second floor, or when I'm outside on my porch, always 4 or 5 bars though, no matter how I hold the phone. Love Verizon and the Tour
