On an Iphone 4, I have no reception for voice calls with 3g off. But I get full reception when I go to the settings to enable 3g? Isn't 3g only for data? Why do I need it on to get reception for voice calls?
I have trialed this on multiple phones and it is always the case that 3g needs to be enabled.

While you do not need 3G enabled to make a voice call, the quality of the call is much better than it would be on EDGE (2G).

You live in a highly populated area so it is possible that 2G may not work effectively there. Either the 2G network is saturated or they have limited spectrum for refarming. I know New York is in decomission stage. AT&T needs to move people off the less efficient older technology.
