Hey, I did a little more investigating and found this thread:

over at XDA. You don't need to bother with all the lines and codes at all! Just open the weather database editor, enter your state (HI) and the name of your town, and then for the location code, just enter the zip code! I tried it with Mililani and it works like a champ. I also tried it for some other small towns that wouldn't work the other way and they worked too. Hope this helps.
