Is that a Nokia Lumia 1520 bulging out of your pocket? If so, you may want to pull that sucker out and check for an update, because Nokia just announced that it’s pushing some fresh software to its 6-inch phablet. According to Nokia’s support site, the new Lumia 1520 update bumps the device’s firmware up to version 1028.3534.1347.2001. The changelog is both brief and vague, including just one bullet point that lists “General performance and usability improvements.”
