Apple’s $99 per year MobileMe service lets Apple iPhone and iPad users syn their email, contact, and calendar events with the web. But it also has a pretty nifty “Find my iPhone” feature that lets you login to the web site and physically locate your iPhone if it’s gone missing. Whether your phone is hiding between the couch cushions or traveling away from you in the back seat of a cab, the service can help you track down the missing phone, send a message to the screen, or even lock down the phone so nobody can access your data.

Today Apple launched a mobile version of the Find my iPhone service, which means you can do all of those things from your iPhone or iPad. Of course, this is only really useful if you happen to have a second Apple iOS device. But it means that you can use your iPad to track down your missing iPhone or vice versa.

In order for Find my iPhone to work, you’ll need an iPad or iPhone. The iPod touch need not apply, since it doesn’t have the 3G modem and GPS functionality you need for a service like this to work.

The Find my iPhone App is available as a free download from iTunes, although you’ll still need to pay for a MobileMe account for the service to work.
