Samsung promised that the Galaxy NX would reach the US, but it didn't say exactly which wireless networks the American model would support. Thanks to the FCC, we now have a good idea. A variant of the mirrorless Android camera has just surfaced at the agency with AT&T-capable LTE and HSPA data. There aren't any clues as to the launch date, although we'd expect the NX to ship relatively soon. Samsung only has a few days left to make its October release target -- barring a last-minute delay, the FCC approval is coming just in the nick of time.
