Apple thwarted Google's effort to release Latitude—which allows your control-freak friends to know where you are at all times—as an iPhone application. You can only update it manually using a web page, which makes it not-so-useful. Until now.
Developer Nat Friedman thought the same as you did (something along the lines of "f*cking stupid Apple morons"), and spent the weekend writing a script called playnice. The script will get the iPhone's location information from MobileMe, then sends it to Google's Latitude. Obviously, it only works if you are a MobileMe user, making it less useful for the rest of the mortals who are not willing to pay more dollars to Steve and his minions. [playnice via Nat Friendman]
