The long-awaited Android Ice Cream Sandwich firmware has already begun hitting Samsung Galaxy S II devices in some parts of the world, and the Skyrocket was lined up to become one of the next devices on AT&T to get the update. The official ROM is now available to download and install, but it wasn’t released by Samsung or AT&T.Instead, Android 4.0.3 was released by developer site RootzWiki earlier today. While it may not be an official release, it is claimed to be the official, “fully functional” firmware. Everything seems to be working properly on the ICS-flavored Galaxy S II Skyrocket. The Android 4.0 version comes with some heavy skinning courtesy of TouchWiz, nothing too shocking considering this is a Samsung device. In this update, there’s the added support for NFC with Google Wallet, which will allow you to pay with your phone.
