Last night, I followed every detail of this guide and it really worked. Might I also add that I have not experienced a single problem with 4.3 so far. I was really afraid of running into all the issues everyone has been posting about, but my phone works totally fine so far. Functional wi-fi, no annoying popups, and no random starts. I did run into a few issues when following the guide where I was getting a "status 7 error" from applying the update from the external SD card. But I went back and restored the phone to stock firmware, rerooted with De La Vega, etc. Seems like it's gotta be totally clean and unmodified from the start in order for the 4.3 OTA to apply. Again, so far so good...
