In this short post I'm gonna present my view on the current Android development stage on Android 4.0 on Galaxy S Advance I9070.
First of all, my device was purchased from Polish carrier PLAY. This flavored ROM still has 2.3 gingerbread. How ridiculous it may sound, the ICS version is not going to come soon in Poland...
There was an official version for pure PL version of 4.1.2 - XXLQE which was a mess.
My advice - do NOT install this ROM - I9070XXLQE has some modem issues - it looses coverage, the 3G does not work. It's a total disaster and was pulled of Samsung Air....

The stable release I'd found is the Russian version: I9070XXLQ4.
