With my extreme dislike of the official ICS rom for the T-mobile T989 Samsung galaxy s2, I have started moving much more to the developer side of the phone use. I have been looking around to find a good rom for our device using the latest and greatest of ICS - as far as I know the latest version of ICS released by google is 4.0.4 which makes numerous improvements on 4.0.3. Most notably battery and speed improvements. Most roms I find are either variation of Gingerbread or 4.0.3 ICS. Are there any good roms that you have found to work with 4.0.4 and do not have very significant drawbacks?
