The folks over at Computerworld just ran the current 3G providers in America through their paces, only to discover that AT&T came out on top in almost every category. Well, it appears the monolithic telco plans to keep its edge (er...) on the competition -- by upping its HSPA service to a whopping 20Mbps come 2009. Our main man Ralph de la Vega said that the process wouldn't require a major overhaul to the provider's infrastructure, and that they're already working on punching up the current 3.6Mbps speeds to 7.2Mbps "in the labs." Apparently, this won't stall plans for forthcoming 4G / 700MHz / LTE service from the company -- it'll just be icing on the cake.

Shortly after beginning the shutdown process of AMPS and TDMA networks, and just hours before the launch the EDGE-capable iPhone, a number of users are reportedly seeing dramatic increases in EDGE throughput. After questioning whether the mobile was actually using WiFi, a New Yorker began to see if fellow AT&T customers across the nation were also noticing the substantial boost in speeds; sure enough, it looks like quite a few others are seeing speeds upwards of 200Kbps. Of course, the usual banter over the legitimacy of speed tests conducted on mobiles inevitably ensued, but we're leaving it up to you. So, dear readers, hop on AT&T's 2.5G highway and give it a go, but be sure to return and let us know whether the increases are for real.

Update: We tried some speed tests on an EDGE handset ourselves, and though it's been a little inconsistent, we've been shocked to find a number of runs over 200kbps. True, these kinds of speeds are theoretically possible (actually, little known fact, the ITU technically defines EDGE as a 3G standard), but we'd never expect to see them in practice. Should make the iPhone's browsing experience a little more bearable if it holds up!
