Galaxy S ICS LogoIce cream Sandwich update will arrive to all the phones which are supporting the Gingerbread 2.3 was the statement by Google Inc. when it had unveiled the Ice Cream Sandwich 4.0 which is the latest version of Android OS for smart phones after the Gingerbread release which was 2.3 version. If you are just thinking on why honeycomb 3.1 will not be arriving for the smart phones then the reason is that Honeycomb is a tablet specific Android version and doesn’t support the mobile phones or say smart phones.

This is a proof that Samsung Galaxy S GT I9000 is indeed one of the phones which will be receiving the ICS 4.0 sooner than later.

    Do I really have to downgrade to XXJVT? I already have XXJVU installed. And does it compatible if i backup using CWM on XXJVU and then restore on ICS? if not, how do you backup the apps with its data if you’re suggesting? And does it take more RAM?

    Lock screen, touch screen sensors and the correct screen resolution are the only things which are working in this Port. No application works but the back key as well as the menu key works.
