With all this talk of searching, just wanted to put this out there. It's the first way I always search for phone stuff and usually it leads to a hit. It's a google search tool by Hypnotic2000 that only searches XDA, PPCGeeks and MobileUnderground.

Edit: So it doesn't search MobileUnderground. I thought he said he was going to add it, but I guess not. Weird, I don't see why he wouldn't.
