Last summer, I mentioned that TeamWin member Agrabren was bringing the ever-popular HDMwIn back to the HTC EVO 4G since full HDMI mirroring had been missing since the Gingerbread OTA update. Since then, kernels like Freedom and ChopSuey have incorporated the HDMI mirroring that he ported to Gingerbread.
Both of these kernels are fine and dandy, but what if you just want a stable stock one with HDMI mirroring built-in?
Well, then, PoonSense would be the answer. It's a completely stock 2.3.3 kernel with that one feature added. And it couldn't be more simple to use. All you have to do is plug your microHDMI cord in to the phone, and you are off and running. You should immediately see everything that is on your OG EVO on your HDTV.
If you're like me and like stable products that you can count on, grab PoonSense from Kernel Manager Lite or from this download link. And if you're into the kernel developing game, you can find PoonSense's source here.
