Well as usual you don’t have to wait for the latest version of the Android Market to hit your device you can download and install the APK now. A few noticeable changes are that you Will now have the ability to select auto-update for your apps as a default selection which will let you choose whether you want this to happen via WIFI only or WIFI and 3G. Another notable change is that when you download an APP it Will automatically add a shortcut on your home-screen (seems as if this is ripped from Honeycomb). If you don’t want to install this APK it will probably appear on your device one day automatically but if like me you want it all now hit the source link up.
