Earlier this year we announcedGoogle Latitude, a service that lets you and your friends share your locations with each other. You control who gets to see your location and where on the map you appear to others. Today, we're releasing Google Latitude for iPhone and iPod touch, available in the Safari browser.
Visit google.com/latitude from your device to start using Latitude. Add a bookmark to your home screen to quickly launch Latitude. Just open Latitude in Safari and tap the + icon > Add to Home Screen > Add. For more details, check out the Google Mobile Blog.
