Is there any chance that someone in your area has a cell phone jammer? I.e., do phones from all other carriers (particularly CDMA carriers) also get poor reception on your street?

This probably isn't the case, but if you live near a school, theater, or similar place, you may want to investigate.

BTW, cell phone jammers are illegal in Canada, and if you call the CRTC, they should be able to locate the device and charge the user.
