For those who have SI Number in the list but can't update. Problem Solved.
Just go to:
http://www.sonymobile.com/gb/tools/update-service/
Download SUS - Sony Update Software and install it. Just run and "voilá".
If you have any questions just ask me.

Please you need to download the last version of SUS.
Version: 2.11.12.5
Is in that link.
Give full uninstall of SUS, restart your PC and install the newer version of SUS.
When you install it the SUS will update for a newer version that cannot been downloaded. Wait and try to update ICS. Please post the result's.
Correct. 
Sorry, but even following your "instruction" step by step there is no update!!!
I wish you were right 
Wich OS do you have?
windows 7 professional 64...
same here.. no update still now
Maybe it has some issues with this version of Windows 7. The Windows 7 32bits has some issues with Sony applications like PCC - Sony PC Companion, so i think it's the OS. You can try to change the compability of the .EXE file.
- Righ button on EXE file.
- Properties
- Compability
Then, put:
- RUN as Administrator;
- Run this program as WINDOWS VISTA Service pack 2.
Then tell me the results.
Nice try! But no effect. I will get accses to an windows 7 32 bit and test the whole there. Maybe there is a chance! I will report...
Thank you for your effort.
doesnt make any sence to me when the software is saying ur phone has the latest software installed. worst part is sony support guy's are tottaly quite on this part. this seems to me the worst support forum i have ever seen where all support guy's dont even intarested to answare to the problem customers are having. but they are keep updating SI list.. tottaly nonsence
In tha't part i agreed with you. The solution that i have apointed just work for those who already have the SI Number in Sony List. CHeck your's.
