Google Maps 4.1 for Android:Brings In Search ‘n Swipe, Latitude Widget And Ability to Switch Google Accounts.
The new search page has done away with the tabs and presents all the info in a single page, making it more suitable for mobile use. You walk through the results by swiping left or right with your finger, neat.
The other significant change is the Google Latitude widget which makes finding your friends or checking the traffic conditions a breeze.
For people with Android 2.1+, they could turn the phone wall paper into a constantly updating live map, with the Maps Live Wallpaper.
