Samsung's Galaxy Note 3 and Galaxy Gear devices aren't available in the U.S. yet, but if you're a developer and/or open source enthusiast, you can already play with them. Sort of. As usual, Samsung has posted the open source kernel files for the new smartphone and smartwatch in a very timely matter, just a couple of days after international availability.
Two Galaxy Note 3 models have been posted so far, the SM-900T and SM-900W8. To be perfectly honest, we don't know which particular variant of the Note 3 these are, but the "_NA" rider implies that the 900T intended for the American market (LA is probably Latin America). Previous FCC files indicate that these are GSM models, but we'll probably find out when the various models launch on American carriers starting in October.
The Gear runs a highly modified version of Android, so you can expect to see a lot more smartwatch kernel posts as Samsung updates and expands the mini-platform and publishes the required code. Whether or not that means people will be able to modify and install custom software on the Gear, as has been the case with Android for basically its entire 5-year history, remains to be seen. At least developers and modders will get the chance to try.
