I think the deadest cellphone zone is in my apartment, and in my office (all the places I need to use my cell phone). But Park Slope is full of dead zones. I’ve got an AT&T iPhone and that could be part of the problem.
There’s a cool article in today’s issue of The Wall Street Journal, “The Worst Cellphone Dead Zones.” It inclues an INTERACTIVE feature online that lets users check the coverage on a block-by-block basis.
Here is a link to the article: http://online.wsj.com/article/SB10001424052748704269204575270562789713490.html
