I just posted this in the "extras" forum. This will take your selected OmniFocus action and cause it to turn into a Toodledo todo. From there you get the warnings via SMS on your cell phone and can use it in your toodledo app on the iphone or the appigo todo list app. It does not sync, but just creates a one way todo with warning.
