New York Today: Can You Hear Me Now? Soon you may long for the squeal of train against track and the squeak of underground rats. Complete cellphone service is coming to the subway system. AT&T and T-Mobile USA customers can already gab away at 36 stations; this week Verizon struck a deal to join them. Coverage for all 277 underground stations is expected by 2017. But do you want it? Do you dread it? The Parisians can handle it - can't we? We want to hear from New Yorkers who already make calls underground, and from those who hate the whole idea. Share your thoughts in the comments section, by e-mail or post them to Twitter with the hashtag #NYToday. Double points if you do so from a subway platform far beneath the street.
