If you've been thinking about subscribing to Apple's MobileMe service just to get the peace of mind that comes with Find My iPhone, there's an alternative that's $84.02 cheaper.
It's called iHound, and it tracks lost and stolen iPhones.
This app's been around for some time, but like similar tracking tools, it suffered from one major shortcoming: it couldn't run in the background, and therefore couldn't transmit its location unless it was activated. (I don't know about you, but I rarely run my tracker app before I lose my iPhone.)
Now that iOS 4 has arrived, however, iHound can communicate automatically, at regular intervals, even when it's not running. And it does exactly that, sending location data to iHound's servers every few minutes. (Thankfully, there are other interval settings, including 10 minutes and 30 minutes.)
If your phone does go missing, you simply sign into the iHound site to see its last transmitted location on a map. You can also send a push notification with a custom message and even a spoken alert. (Example: "This...is...iHound!" That should get some attention.)
There's even an option to remotely activate a siren, which could help you find a misplaced phone--or startle a thief into ditching it. And the siren can be deactivated only from the site (though an iPhone-savvy thief could simply turn the volume down to zero).… Read more
