I've kinda sorta almost have Macintosh Dashboard widgets running on the iPhone. Some run okay, others not so much. The Weather, ESPN and Calendar widgets are some of the best; the Flight Tracker, Dictionary and Phone Book are among the worst. If you'd like to give this a try, download a copy of Widgets.app with the following understanding:
- Widgets uses the XLaunch icon and splash screen and the Unknown icon is the wrong size. Sorry about that.
- You must install System/Library/WidgetResources from your Mac onto the iPhone. Same folder, same name, same contents. Most Widgets will not run properly without these support files.
- Install your widgets into /var/root/Library/Widgets on the iPhone. Widgets.app runs plain old ordinary OS X widgets. You must copy over the entire file structure, so
scp -r YourWidget.wdgt root@youriphoneip:/var/root/Library/Widgetsis going to be your best bet. And yes, you need to create the Widgets folder if it does not yet exist.
