I have an iPhone 4 (not the one with Siri) and keep it updated. On the most recent update, the old URL scheme (which lets you make nifty shortcuts to settings) stopped working. Does anyone have a fix for this?
Right now I am not aware of anyone having come up with a different solution that works like the old profiles (what you call URL scheme shortcuts) did. There have been a couple of discussions on the forum about them as well, as many people used them.
