We’ve got an Android 4.0 ROM (in alpha version) for our international version of Galaxy S2, i9100, but our friends at T-Mobile in US who have a slightly different version of S2, are yet to get one true AOSP Android 4.0 ROM for their Galaxy S2. But fret not, if you’ve got the Galaxy S2 device at T-Mobile, there is a custom ROM to ease you for the time being,  till real Android 4.0 firmware/rom is out.

Called Domination — it’s got the ICS theme, which makes it look very much like an actual Android 4.0 ROM, and it’s faster, no-bloatware ROM, based on Android 2.3.5 with Samsung’s beautiful TouchViz 4 UI. It’s not based on Android 4.0, ice Cream Sandwich, btw, in case it needed repetition.
