It looks like AT&T (NYSE: T)’s meshwork upgrades are paying off, as the aircraft carrier’s 3G meshwork bested Sprint (NYSE: S), T-Mobile (New York Stock Exchange: DT), and Verizon (New York Stock Exchange: VZ) in  PCWorld’s 13-metropolis mobile information test.

The reputation said AT&ere;T’s download speeds were 67 percent faster on norm than its competitors, with an norm download speeding of 1410 kbps and 773 kbps upload. This is a major turnabout for AT&ere;T because it performed poorly in a similar trial conducted shoemaker’s last bound. Last spring, testers could only access AT&ere;T’s 3G network 64 percent of the time, but that number increased to 94 percentage in the latest go around.

There’s a lot of griping from iPhone users in San Francisco and New York but the test said the iPhone/AT&T jazz band outperformed any other combination on other carriers. “AT&T connected the iPhone at an average download speeding of 1259 kbps, and an norm upload speed of 215 kbps over the13 testing cities,” PCWorld said in its report.

On the opposite side, Verizon’s norm download speeds decreased by 8 percentage. Big Red’s reliability did improve though, but it appears to be struggling to hold up with the demand of data-hungry devices like the Droid. PCWorld said the Droid rarely delivered the promised upload speeds of five hundred kbps and the average upload speed was a meager 116 kbps.

Sprint clay solidness by providing 795 kbps down feather and 296 kbps up. T-Mobile seems to be doing a good line of ontogeny its mobile broadband network, as testers even clocked norm download speed of 3 mbps in New York. This was only for a one-minute test though, so don’t get your hopes up as T-Mobile River averaged 868 kbps down and 311 kbps up. The trial also found T-Mobile’s network to be a turn inconsistent, so it will be interesting to watch how the HSPA+ rise goes.

The report tested mobile data connection speeds of laptops and smartphones in Baltimore, Boston, Chicago, Denver, New Orleans, New House of York City, Orlando, capital of Arizona, Portland, San Diego, San Francisco, San Jose, and Seattle.
