The device itself won't be available for another couple of weeks or so, but Samsung has wasted no time in releasing the Linux kernel source (and other open-source bits and pieces) for the AT&T Galaxy Note. The AT&T Note (aka SGH-I717) sports a slightly different hardware setup to its international counterpart, the GT-N7000, hence the difference in behind-the-scenes code. As per the open source rules, the code is freely available for anyone to grab over at the Samsung Open Source site.
Though source code isn't a whole lot of use without the device itself, at least this early code release should jump-start the AT&T Galaxy Note ROM scene once the phone launches. Speaking of which, it's due from Feb. 19, for $299 on contract.
