Samsung made much ado of the Galaxy Camera coming in both 3G and 4G versions, but it wasn't clear just which carriers would let us upload photos when away from WiFi. The FCC might have just given out a big clue with approval filings for two 3G editions. As it's been tested for US clearance, the Android point-and-shoot in its EK-GC100 and EK-KC100 guises has support for HSPA-based 3G on the 850MHz and 1,900MHz bands used by AT&T and larger Canadian carriers -- a possible hint of Big Blue's ongoing connected devices push, but not a very promising discovery for most T-Mobile users or any CDMA customers. Before anyone bemoans the absences of LTE or support for more American networks, however, we'd note that this is just one filing and might not represent the totality of Samsung's US plans, if we're indeed looking at one or more US-bound examples. We'll keep an eye out ahead of the Galaxy Camera's international launch in October to see if there's anything more in the FCC's cards.
