We know that Samsung is rolling out Ice Cream Sandwich Updates to Galaxy S2 devices all over the world. However, the updates are being rolled out based on location starting from Europe where the official XXLPQ was released and later developers had ported it to the international Galaxy S2 variant. SkyRocket was released for AT&T Galaxy S2 i777 but we did not write about it as there was yet another official leak for AT&T Galaxy S2 which is a stable one. The same SkyRocket has been ported to T-Mobile Galaxy S2 SGH-T989 by XDA member Racing19969. Please note that this ROM can be applied only on T-Mobile Galaxy S2 and not on any other variant.
