That was a good read. I spend a lot of time in the interior computer labs at the school at which I teach, and those cinder-block walls kill reception with AT&T...though not as bad as Sprint or Verizon here in D/FW though. My iPhone 3GS here gets better reception than Verizon and Sprint iPhone 4S in the same spot, so this should be a good sign if I get this phone or the HTC Vivid with my pending upgrade. Thanks!
