!!!MAKE SURE YOUR PHONE IS PUT IN USB DEBUGGING MODE!!!

Warning It's your phone if you break it blame yourself. I can't help you if this script bricks your phone. I have used and it worked great.
Currently there is no recovery, no roms or way to make a nandroid backup. BE CAREFUL. REALLY.
You will need the proper adb drivers for this to work .

1. Put your device in usb debug mode from developer options setting menu.
2. Download DoomLord Script and extract it to a folder.
DooMLoRD_v1_Xperia-2011-ICS-ROOT-emu-busybox-su.zip
3. Connect your phone via usb and make sure you have adb drivers already installed.
4. Open the extracted folder run the runme.bat
5.Click any key to start the script the device will reboot be patient can take a couple minutes.
6. After script completes hit any key script should close you now have root.
