Samsung had recently confirmed the official release of ICS for the Indian version of Galaxy S2 or we can say I9100G. This particular version of Galaxy S2 is somewhat downgraded form of the original Galaxy S2. It features TI OMAP chipset from Texas Instruments and features a under powered GPU PowerVR SGX540 as compared to the originals Mali 400 GPU.
But still this is the only official S2 available in India right now and also the only the official S2 in India which has the ICS update. It is also a known fact that the ICS update for I9100G is already available in some of the countries in which it is available but now it is confirmed that loyal S2 users from India can also taste the all new ICS on their S2.
