I929 has almost the same specs as SII as mentioned in Samsung I929 Galaxy S II Duos with dual-network support pops up - GSMArena.com news (not exactly though) and the specifications are mentioned HERE .... It should be soon launched worldwide. I am guessing if two GSM sims will fit or just one cdma and one gsm! But this will be the most powerful dual sim phone for now. Dual sim phone users will love it.
