Rumours have started to filter out about the release of Sony Ericsson’s upcoming Android handset, the XPERIA X10. Though nothing that can be called as concrete evidence has come out yet, it appears that the X10 may be available soon subsidized by major US carriers. Sony Ericsson is supposedly working on two variants of the smartphone, possible to cater to the needs of AT&T and T-Mobile. Since both versions are to have 3G support, the T-Mobile version will support the 1700 MHz band used by T-Mobile 3G network. Sony Ericsson has plans to bring out the XPERIA X10 in early 2010.

One of the biggest features of the Motorola Droid ( running Android 2.0 ), was the Google Maps Navigation app which offered turn-by-turn navigation features for free similar to what is offered by many other paid applications such as those from TomTom. The app comes with everything you would expect to find in a traditional GPS navigation system and has 3D views, turn-by-turn voice guidance for use while driving and automatic rerouting in case you miss a turn.

Now the same app has been made available to the users with phones running on the Android 1.6 software, such as the T-Mobile G1, myTouch 3G, Motorola CLIQ etc. Those who are using the HTC Hero or Eris will have to wait out for HTC and your respective carriers to put out an Android 1.6 update before you get to use Google Maps Navigation.
