But clearly it's the best we got. I'm not going to argue the statistics but I can tell you for sure that Qwest users in Scottsdale often report Peoria and Business Qwest users in Scottsdale report Phoenix (though Phoenix probably falls within the 25 mile accuracy level). The 1000+ it has resolved on my website are mostly impossible to tell the accuracy unless I know for sure which connection is which and I rarely do. Proxy services such as AOL completely defeat identification (I get the country). Why anyone actually still uses AOL software I have no idea but yes, they do identify as USA. Mobile carriers simply don't identify well at all. They only give me USA. Blackberry web users are few and far between though. For example, a Sprint customer (68.28.59.112)... {:country_code=>"US", :longitude=>-97.0, :country_code3=>"USA", :latitude=>38.0, :country_name=>"United States"} Blackberry...68.171.233.24 {:country_code=>"US", :longitude=>-97.0, :country_code3=>"USA", :latitude=>38.0, :country_name=>"United States"} Verizon is no better Just saying...
