Update Nov 2016: looks like this doesn't work anymore.

The easiest and one of the most powerful ways is using http://debug.phonegap.com (it uses Weinre in the background, if you care). You just

1. pick a random string, say r4nd0m,
2. inject into your index.html
3. visit http://debug.phonegap.com/client/#r4nd0m and you will instantly be debugging your mobile web app.

Things you can do (similar to Firebug or Web Inspector):

1. Viewing and changing the DOM
2. Editing CSS
3. Console for live debugging and running Javascript remotely.
4. Other stuff, like: storage, resources, timeline, profile, etc.
