As of 2009, only 4 phone booths remained in Manhattan: http://www.scoutingny.com/the-last-phone-booth-in-new-york-c... Comments on that thread note that in 2012, at least 2 of those were verified as still around, but not sure about now.

There are a lot of phone stalls still around though - a number of which have been sites for experimental improvements for some time now, including a Google initiative to outfit some with public wifi: http://www.nyc.gov/html/doitt/html/business/future-of-public...
