If you can't wait to try out Gingerbread on your HTC EVO Shift 4G, then you can start doing a "happy dance". Gingerbread for the device was leaked, and a custom ROM has already been created by some folks over at XDA Developers. As long as you are rooted and ROM'd, you can easily give the custom flash a shot. Just make sure you let us know in the forums what you think.
