Well maybe they won't downgrade you but you can downgrade back to Gingerbread manually
I have 6.0.A.3.75_O2 UK Firmware which was the last UK Gingerbread firmware released before ICS all you need is Flashtool and that firmware and the drivers installed
To check power off your phone, Hold Volume down and connect the USB cable - If the drivers are installed then device manager will not have any errors or yellow warning symbols
If interested reply and i'll post a link to the firmware with fast download speed

I got the same answer by phone from Sony support in Sweden.
Then I googled around and solved it myself. Maybe Sony should hire me :smileywink:
Here's how I did. without rooting the phone:
1.Downloaded a new ftf:
(worked as a charm for me in Sweden, dunno which countries it supports,think I saw Belgium though)
2.Downloaded and installed Flashtool + update
3.Also needed to install some driver:
checkout and follow instructions:
After all above,
4.I unzipped the ftf into C:\Flashtool\firmwares
5.Started flashtool and pressed the flash-button
Be sure to FOLLOW all onscreen instructions !!
And now I am a happy Xperia S-owner again with GB.
Don't ask me any questions about above, all is written on the pages or as instructions in the programs.

Instructions (Ignore the debrand name - It's the same for any manual upgrade and or downgrade)
Also if you do downgrade you will have to wipe user data and start fresh as ICS settings will be carried over and will cause some serious problems
If you get stuck or are unsure reply back

Any chance of explaing why
I already know the answer but lets hear your reason for other members before I post the official reason

So Sony is been a big help - Typical, They push out a rom that is full of bugs which they know about and won't offer any help - Well this is known as an inherent fault caused by software which by UK law gives you the ability to cancell any contracts or claim a refund,
Acer fell into this trap about 2 years ago with there bios updates sony have done the same with there ICS update
Proof of an inherent fault is here in the forums many many many members reporting the same issues which then becomes an inherent fault
