TeliaSonera has today flicked on the green light for its LTE networks in Stockholm and Oslo, officially starting the countdown for LTE-enabled phones. For the moment, keen mobile webstronauts will only be able to hook up their laptop or other USB-equipped device via the Samsung-provided 4G modem, but 100Mbps download speeds on the world's first commercial LTE network are still nothing to sniff at. This rollout is in fact slightly ahead of schedule, and the other major cities in Sweden and Norway are likely to soon get treated similarly well, while TeliaSonera makes a point to mention it has a license to do similar damage to Finland's 3G operators. The US might not be too far behind, either, given that the modem in use in Scandinavia recently cleared the FCC. Now if only we had phones that could ride these massive waves we'd be all set.
