At the end of January next month, we will be seeing at least one very cool new smartphone in the market, where you can say that it is RIM’s last stand where their Blackberry brand name is concerned. The BlackBerry 10 platform will be launched then, and we do hope to see some pretty cool hardware end up as part of the equation. Well, the folks over at the FCC have apparently put an unnamed BlackBerry device that sports a RFF91LW model number through the paces, while giving their collective nods of approval for it to play nice with AT&T’s LTE and GSM bands, in addition to a few other international frequencies, of course.

This handset’s label sample has been censored (how convenient), but the FCC reports do point that there were, at a minimum, three different devices from RIM which were powered by BlackBerry OS 10.0.9. Could these FCC-approved handsets actually be the “L-series” BlackBerry Z10, or is it a false lead in the sense where it is part of the Dev Alpha device range that RIM dished out to developers? Stay tuned to find out.
