That's the plan! Right now we're in the process of collecting phones from mobile manufacturers for testing. We want to, first, add these devices into our development and testing workflow so that we can support them fully. Once we've done that we'll be able to start shipping custom mobile-tailored builds of jQuery that strip out unnecessary code and add in mobile-specific stuff.

Ideally though we should be shipping a single JS file that you can embed in your web site and know that it'll work on both the desktop and on a smart phone.
