If there's one thing AT&T's network could use, it's more network. Particularly in major cities (we're looking at you and your dastardly street parking situation, San Francisco), AT&T's 3G network is perpetually overwhelmed, oftentimes forcing users to switch to EDGE just to tweet about how awful the coverage is. Thankfully, the operator is making good on its earlier promise to roll out HSPA 7.2Mbps to select cities, with Charlotte, Chicago, Dallas, Houston, Los Angeles and Miami now destined to get lit this year. Potentially more interesting, however, is the deployment of "additional backhaul capacity to cell sites," which will also support LTE when the time comes. All told, around 2,000 new cell sites should be added before the year's end, and at least a half dozen 7.2Mbps-capable smartphones should be in AT&T's portfolio by the same deadline. Feel free to express your joy in comments below -- that is, if you can get comments to load on your existing 3G connection.

Mmm, the sweet smell of mobile data burning up the pipes in the morning. Gets us every time. Evidently, the same aroma does something to the brains of Ericsson and TeliaSonera, who have taken their January agreement to the next level by introducing the planet's first commercial Long-Term Evolution (LTE) site in Stockholm, Sweden. Mind you, we've seen lots of trial runs over the past year and change, but this one's no test. Rather, this site will become part of a commercial network scheduled to go live in 2010, bringing wicked fast mobile transfers to Stockholmers everywhere. Now, let's hope these American carriers get jealous, and fast.
