Count me in the ranks of those who get a lot of dropped calls on AT&T (both Blackberry Bold and now Google Nexus S). So I look with interest on all the comparisons journalists are doing between AT&T and Verizon for iPhone dropped calls. David Pogue finds a huge advantage for Verizon.

I took the Verizon iPhone to five cities, including the two Bermuda Triangles of AT&T reception: San Francisco and New York. Holding AT&T and Verizon iPhones side by side in the passenger seat of a car, I dialed 777-FILM simultaneously, and then rode around until a call dropped. (Why that number? Because I wanted to call a landline, eliminating the other person’s cell reception from the equation. Also, Mr. Moviefone can carry the entire conversation by himself, so I could concentrate on the testing.)

In San Francisco, the AT&T phone dropped the call four times in 30 minutes of driving; the Verizon phone never did. The Verizon iPhone also held its line in several Manhattan intersections where the AT&T call died. At a Kennedy airport gate, the AT&T phone couldn’t even find a signal; the Verizon dialed with a smug yawn.

Pogue points out that as millions flock to Verizon for their iPhone version their comparative advantage might decline.

Walt Mossberg also finds a big Verizon advantage.

On the big question, I can say that, at least in the areas where I was using it, the Verizon model did much, much better with voice calls. In numerous tries over nine days, I had only three dropped calls on the Verizon unit, and those were all to one person who was using an AT&T iPhone in an especially bad area for AT&T: San Francisco. With the nearly identical AT&T model, I often get that many dropped calls in one day.

A friend got a pay-as-you-go plan with a cheap phone on Sprint in order to compare. His dropped call experience on Sprint is much better. When we have phone conversations between our AT&T phones with 4 bars each the dropped calls make the conversations painful. I am waiting for my contract to expire.
