There hasn’t been much word on the next generation Android OS 2.0 also known as Donut, and there have only been whispers on the future released of the Android OS “Éclair and Flan” however according to an article on the WSJ, Google VP of engineering, Andy Rubin says the social element will be a big focus.

The word is that the social push will pull caller ID images from social network sites such as Facebook and use profile pictures which of course the BlackBerry and Palm Pre already does.

Yet another significant extra could be the inclusion of carrier billing for mobile applications bought in the Android Market; as yet the only payment option is Google Checkout but using this way a user can purchase all in a single swoop.

Oh, by the way, Rubin also confirmed that there will be 15 to 20 more new Android platform smartphones before the end of the year.
