I confirm this is exact Retail version we have on our phones in India.
Now any devs here who can please create a custom ROM based on this? For those who don't know, Indian firmware doesn't have any restrictions like AT&T. Hotspot, network selection, *#*#4636#*#* menu all work absolutely fine, no bloatware or AT&T crap either. Indian hardware works fine with AT&T firmware so AT&T hardware should work with Indian ROM as well, with no issues.
I request any Devs here to please make a custom ROM out of this Indian firmware. Once it is properly tweaked and modded I know it will be best and most popular ROM for our beloved Atrix 2 so far.
