Looks like someone has some time no their hands as they went through that Long Zheng WP7 emulator video and "ripped" the audio for the ringtones and alarms, then trimmed them into individual files. Whew!
Now a couple of caveats: these aren't the most exciting ringtones/alarms, in fact they all have a similar theme to them. Second, there's no way to know if these will be the "final" tones on board Windows Phone 7, indeed, it's probably a safe bet that they're not.
But hey, they're new, they're free and they don't sound half bad, so go for it. Grab 'em here.
