Nicknrm, I do not mean to disrespect, but you are incorrect in that the phone has nothing to do with reception. I currently live in between two At&T towers right at the edge of signal fallout. I cannot talk on a cell phone inside my home. For the past 2 weeks, I have bought and returned a different phone EVERY DAY from the AT&T store, attempting to find one that gets good reception. Turns out, the phones with external antennas (such as the Motorola Tundra) often had 3 bars where the phones with internal antennas had 1 or 0. Although I despise the Motorola Tundra (awful call quality, speaker problems, and text message alert issues) due to its external antennae I was able to talk inside my home comfortably with decent reception, whereas other phones could not even place a call.
I saw this trend with every phone I tried. Any phone I used with an external antenna worked inside my home, and any phone I used without an external antenna didn't.
