However, it's in the form of a Web app and not a native app
Almost six months after introducing Google Latitude, current location broadcasting service for users, Google has finally rolled out Latitude for iPhone
OS based devices.
Google's Latitude service has been made available for download to iPhone and iPod Touch owners in the form of a web app and not a native app. On heading to google.com/latitude though the Safari browser, the iPhone or iPod Touch owner will get the Latitude will show up. Note that Latitude is different from the My Location feature recently added to Google for iPhone users.
Mat Balez, product manager of the Google Mobile team, noted in the blog post at Google Mobile Blog that Apple requested them to release Latitude as a web application in order to avoid confusion with Maps on the iPhone which uses Google to serve maps tiles. As noted in past, iPhone OS 3.0 software update would bring Geolocation support in the Safari browser. That might be the reason why Google held up Latitude for iPhone.
Users can add Latitude to their iPhone or iPod Touch home screen by clicking on the + sign at the bottom of Safari browser window and select 'Add to Home Screen' option. Latitude on iPhone being a web app won't work in the background unlike for other mobile platforms like Symbian, Android, BlackBerry and Windows Mobile
. For saving battery life, Google Latitude uses Wi-Fi triangulation or Cellular Tower location instead of GPS.
In case you're worried about privacy, it is being taken care as the user can restrict Safari from using current location. Also under the 'Floaty Bar', users can choose either to Set their location, Detect their location or totally Hide their location from others.
It is hoped many iPhone and iPod Touch owners would be happy to see Latitude on their devices. If in future Apple allows background process on iPhone OS based devices then update on Latitude might include it to native Google Maps app or Google Mobile app from App Store.
Google Earth can now take you to the moon.
Timed with the 40th anniversary of the first moon walk, the Internet giant on Monday released an addition to its Google Earth mapping software to provide images of moon landscapes and traces of human exploration there. 
Called the Moon in Google Earth and available for Windows, Mac, and Linux, the software allows you to see topographical features on our closest celestial neighbor with the lunar equivalent of Google Street View. People can also see a gallery of the Apollo space missions and get information on every robotic spacecraft that has visited the moon. 
"This tool will make it easier for millions of people to learn about space, our moon and some of the most significant and dazzling discoveries humanity has accomplished together," Anousheh Ansari, a trustee of X Prize Foundation and the first female private space explorer, said Monday on a Google blog.
Google is hosting an event Monday to launch the Moon in Google Earth site at the Newseum in Washington, D.C., where Ansari and Apollo 11 astronaut Buzz Aldrin will speak.
To access the images from Google Earth, you select Moon from the toolbar in Google Earth. From there, the viewer zooms down to get detailed images of the moon's surface.
From the left panel, people can surface information about the moon, including historical charts used by astronauts for training and NASA mission control. High-resolution photos break down the moon's surface into different quadrants to show its features.
The tool is designed to teach people about the missions to the moon by visiting the various Apollo landing sites. After zooming into a location, people can see video clips and panoramic stills taken by the astronauts, such as Neil Armstrong's first steps on the moon. Aldrin also offers a guided video tour of the moon from within Google Earth.
The artifacts tab allows people to see three-dimensional models of the spacecraft that have gone to the moon.
The Moon in Google Earth project was done through Google's partnerships with NASA, which allowed researchers to develop much of the content. Japan's space agency, Jaxa, also donated the global terrain dataset for the moon. 
Google has launched the Google Voice mobile app for Blackberry and Android phones.
This new mobile app allows users to make calls and send SMS messages with their Google Voice number directly from their mobile phone, unlike previously where users had to dial their own Google Voice number from their cell phone or use the Quick Call button online. The app is fully integrated with each phone's contacts, so users can call via Google Voice straight from their address book
Features available are:
- Access to voicemail: read message transcripts, follow along with "karaoke-style" playback of messages, read SMS messages sent to your Google Voice number (even if your phone doesn't receive SMS messages) and access your call history
- Place calls that display your Google Voice number from your address book, the app dialer (Blackberry) or the native dialer (Android)
- Send SMS messages that display your Google Voice number
- Place international calls at low rates
The app can be downloaded from the Google Voice mobile site at m.google.com/voice. It's also available in the Android Market.
Foe those not using a Blackberry or an Android-powered device, a mobile web version of the Google Voice site (accessible by typing www.google.com/voice into your mobile browser) that allows you to access Google Voice features, is available.
