Just rooted my SGS2 using the http://forum.xda-developers.com/showthread.php?t=1319653"]DooMLORD easy rooting [/URL]application.
Superb piece of software.
I rooted my Samsung Galaxy S2 ( Indian ) in a flat 4minutes. I was very nervous in rooting the phone having bricked my Samsung i780 in flashing custom ROM and having sent my Omnia i900 nearly to death flashing a custom ROM .... but then the thrill of rooting and modifying the device got better of me and I did it in a flat record time of 4 minutes.
The option of unrooting is an added benefit.
Will it Root my SGS2 (O2) running the new ICS ?
