Has anyone successfully rooted this firmware yet. I have tried to do this but I have been unsuccessful yet.
Any recommendations.
So far I have not had success with zergrush, SuperOneClick, or GingerBreak. i have tried all 3. GingerBreak just sits there. SuperOneClick dosent work. and ZergRush says it works but when I try to make changes or use RootChecker the phone is not rooted.
You are on which firmware ?
4.0.2.E.0.57
i checked on xda and it seems you can't root 2.3.4
but 2.3.3
Is there a roll back procedure so that I could go back to the stock 2.3.3 without voiding my warrantee?
Nopes.....
Sony doesn't provide an option to downgrade 
Well, that suxs.
I have never been completely happy with this phone. I think it has a lot of potential but it was not very well executed.
I hope the ICS update fixes things because I will probably never buy a Sony phone again.
yeah i have successfull rooted r8oox 2.3.3
