A native Google Latitude app for iPhone is soon to be released and should be available in an App Store shortly if it isn't already. Latitude is a service that uses location-based check-ins to let you track your friends online (with all appropriate privacy guards, of course).
UPDATE: Latitude has been pulled from the Japanese App Store. TechCrunch thinks the release might have been accidental and an official, publicized release could be coming soon. Now back to the original post already in progress...
While not the brouhaha Google Voice was, Google Latitude's absence from the App Store had been noticed. Could this mean we'll finally get a Google Maps Navigation and -- dare I say it -- native Gmail as well?
Description after the break.
With Google Latitude, see where your friends are right now. Latitude lets you stay in touch with your friends and family by making it easy to share where you are and see each other on a map.
With Latitude, you can:
See your friends on a map – find out who’s nearby and meet up.
Share your location continuously with whomever you choose – help friends and family stay in touch with you, even when you can’t take out your phone.
Control your privacy – share only city-level location, hide your location, or turn off background updating at any time.
Latitude lets you share your location in the background, even when the app is closed or your device screen is locked. Background updating requires an iPhone 3GS or iPhone 4 with iOS 4 or above.
You can also enjoy Latitude from your computer at google.com/latitude to see where your friends are or turn on optional apps such as Google Location History for a personal history dashboard.
