[REG] Suggestions on a Free Mobile Plugin

I have over a hundred WP sites that I need a good, currently-supported WP mobile plugin to use on these sites. Please list your favorite Mobile plugin and whether it's legitimately free or available here on BHW for me to try out before I buy. Thanks.

Just search mobile optimized site plugins and you'll come across several that will get the job done. Many of them include options to run mobile ads via adsense and other ad networks.

I want suggestions from what YOU BHW members use on your own sites I've tried the whole searching thing, and very tired of seeing people take the lazy way out and say 'google it' or 'search it' rather than just helping a fellow webmaster out for a change.
