Numerous reports made their way onto the web today stating that Sprint's LTE was available in the San Francisco Bay Area: specifically in Mountain View, Cupertino, Sunnyvale, and Palo Alto. Android Police was the first to report the news, and, as expected, it turns out that whatever service customers received today was merely part of system testing. Sprint has let us know that it hasn't permanently turned on service and made a point of saying that it has yet to announce when the high-speed data network will officially be available in the Bay Area. Just like AT&T and Verizon, Sprint has long turned on sites a bit early to conduct some testing — most recently in Atlanta, Texas, and Kansas — and today's service in San Francisco is no different. It's not clear if Sprint intends to keep the sites it tested today on-line until the service officially launches, but we would expect that won't be the case.
