Samsung is still delaying the Global Official release of Android ICS 4.0.3 for Samsung Galaxy S2 I9100 and everybody is waiting anxiously. The update is almost here and while some carriers have already rolled out the update, many users are still on Gingerbread, even though their handsets are among the most powerful devices on the market. It might be a while before we get the official release, so meanwhile, we can have a taste of Ice Cream Sandwich if we install the new beta build entitled Android 4.0.3 XXLPJ for Galaxy S2. In the following step by step tutorial we will present to you the right installation process, but you have to keep in mind that this is not the Global Official ICS 4.0.3 release (for which we have no estimated time of arrival yet), it’s just a pretty stable beta build which might contain some bugs.
