What's the best way to sync Chrome bookmarks to iPhone?

I use Google Chrome on my Mac as my browser, and I'd like to be able to have access to my bookmarks on my iPhone. Safari provides bookmark syncing automatically, and Mozilla has [an app](http://itunes.apple.com/us/app/firefox-home/id380366933?mt=8) that provides that functionality, but I the only thing I can find is [Xmarks](http://www.xmarks.com/) which is a) paid, and b) synchronizes with a third-party service, instead of utilizing Google's existing bookmark sync for Chrome. Are there any other solutions?
