While interesting, I'm not exactly sure why you need jQuery reference on a mobile device. Every single time I have been developing with jQuery I have been on a computer.
I find stuff like this useful as a way to learn more while doing something like riding the bus, sitting in a waiting room, etc. I wouldn't use it while developing, but it'll help me learn while not developing.
Very cool web-app. Interesting use of local db and iphone-specific html stuff. props!
If anyone could point me to similar (iPhone-friendly) references for Objective-C and iPhone development I would be eternally grateful. I've downloaded the PDFs, which a reader like GoodReader does pretty well at, but something like an HTML-formatted guide would be more palatable.
