This was the coolest thing ever:

Also strongly recommend downloading this first:
http://www.freewarepocketpc.net/ppc-...ader-v1-4.html
It gives your phone the ability to read Q codes, which every download on that site will display on the page. Open up i-nigma, aim it at your computer screen, and instantly download the file.
EDIT: Well, after reading some comments, it seems like that locker needs some work to deal with some stability problems, but it's still darn cool. Can't wait for a full version of it.
