Oddly enough, these do not work on the American version of the Optimus 2x (T-Mobile G2x) running the latest 2.3.4 update. They don't even show up on the widget list once I install them. I tried restarting the launcher (I've tried ADW EX and the modified Optimus 2x launcher available on these forums) and rebooting the phone. They show in my apps list when I view Manage Applications in the system settings, so they're definitely installed, but just not working.
edit: must be LG's OS that blocks them, because CM 7.2 nightly for the G2x works.
