As for WiFi, I posted some pics way back when I got my B1 S3s (pretty sure I was the first! 
), showing the controller board with the U.FL connector on it. Can't remember which page it was on but yes, I can confirm WiFi does work, and all you need is a pigtail and antenna. I was going to drill a hole but never got around to it, instead the pigtail is hanging out the same gap the fan wires come from. Might do a more permanent upgrade on my two new B4 units that will be coming my way.
Also, query for Bitmain:
Is the version of CGMiner on the units going to be upgraded any time soon? I'd love to see a more recent version of it or BFGMiner available, preferably one which doesn't absolutely kill the CPU usage on the controller board.
