I travel a great deal and have had a chance to test AT&T's wireless
service in areas such as Dallas, New York, New Jersey, Connecticut, Los Angeles, San Francisco and others. What I have noticed is the service is improving and aside from occasional glitches, surfing the web on an Apple iPhone 3Gs is a more pleasant experience. I don't think it approaches Verizon Wireless yet but then again, VZW doesn't have to deal with the onslaught of wireless data requests generated from legions of iPhone users. AT&T has an opportunity of a lifetime to upgrade its network before it loses iPhone exclusivity (assuming it does).
To say the company is rushing to improve its service would be an understatement - in fact it is doubling its data speed through the use of HSPA in six cities -- Chicago, Dallas, Houston, Los Angeles, Miami and Charlotte. This is great news as the next ITEXPO and - East 2010 and the collocated 4G Wireless Evolution will take place in Miami this January and these upgrades should be in place by year's end. I am looking forward to testing the service out then.
