As far as Android goes, probably the best know app for locating lost devices it Lookout, but there are others as well. I have AVG antivirus on my Android, mostly because it has a free locator feature. You can log on via computer and turn on GPS remotely. I actually tried it just a few minutes ago to see how accurate it was, and it placed my phone in the middle lane of the 4 lane highway going by my office. I think that reflects a poor GPS signal more than a limitation with the app, but if it had actually been lost or stolen I would possibly face the same issue. You can also remotely activate the ringer to give audible guidance when you have narrowed it down.
I think perhaps the most valuable feature of these apps is the ability to remotely lock and wipe the device. From my admitedly casual testing, I would probably not have been able to specifically locate my device, but at least I would have been able to erase any private data so that the damage would have been limited.
