The Samsung Galaxy S II Skyrocket HD debuted on AT&T early this year, and at the time it was rocking Android 2.3 as the operating system. Samsung has been slowly updating many of its smartphones to Android 4.0 Ice Cream Sandwich. The Skyrocket is one of the devices getting the update along with the regular S II and several other smartphones that already have it. I’m sure there are more than a few users of the Skyrocket that worried they may not get ICS, but those fears are unwarranted. The official ICS built for the Skyrocket has been around apparently since March 14, even though it hasn’t officially launched yet. If you are tried waiting for the official launch, apparently RootzWiki has landed an early version of the official update. You can head over the website and get the full leaked update along with installation instructions and links to download mirrors. It won’t work with versions of the Skyrocket operating on the T-Mobile or Rogers networks. The update does add the whole shebang the AT&T version, including NFC and Google Wallet.
