Here’s some good news, folks. AT&T has just announced that they will have full HSPA coverage across their entire 3G network by the end of June. Currently, 275 AT&T markets sport full HSDPA/HSUPA coverage. That number is expected to rise to 350 by the end of next month. If all this sounds a bit familiar, you’re probably on to something. The company embarked on a massive EDGE network upgrade last year, just prior to the release of the EDGE capable iPhone. It’s no secret that Apple’s new handset will sport a 3G radio, and the proposed USP improvements are no-doubt related to the impending launch. As excited as we are, we’d still love to see full 3G penetration across their entire network, but we’re guessing that might take a bit longer.
