No, you missed the point. AT&T can't upgrade all HSPA units to HSPA+ instantaneously. They concentrate on major metropolitan areas in getting the higher-speed technologies, whereas the outlying areas will get attention later. The HSPA gear is eventually deployed in EDGE areas to expand 3G coverage.Exactly the point. AT&T's HSPA coverage isn't anything to crow about. So even though they'll have HSPA+, a good number of people will still be falling back to EDGE (which is slower than EVDO and no simultaneous Voice/Data).
No U.S. carrier can crow about their 3G data performance (or any other aspect of their network). In this year's Consumer Reports survey, Verizon was a 36" giant in a land of 35" midgets. Same with last year's survey. AT&T dropped, Sprint made a little progress, but on a whole, no American mobile operator can be proud of their customer satisfaction ratings.
