Also thinking about downgrading my 2.3.3 version to 1.6, but I can't find tutorial with details for my problem.
Sounds like you're talking about a combination of internal data and the data you have 'collected' on the microSD card.
Stick a SanDisk Ultra 64GB microSD card in your phone, link all your data/apps to a second 2GB ext3 partition on the 64GB card using Link2SD.... job done.
Then you have almost unlimited room for junk in your trunk.
You can always take your microSD card out of your phone and place it in a PC and back it up as it's FAT32 and your PC can read it just fine.
Otherwise, a USB connection to the PC and backup the card that way.
Then you can replace the microSD card in your phone and format it.
Using PC companion or SEUS you can re-install the GB 2.3.3 fw anew.
[Myself] I'd root the phone and then remove all the bloatware in /system/app
This'll make resources available for the 'real' applications and improve the X10i response.
I can think of no valid reason to re-install Android v1.6.
Many applications only support GB 2.3 and greater now and you'll just be creating a whole world of pain for yourself.
I have a pseudo GB 2.3.4 fw build mostly sourced from the XPERIA LT26i on my XPERIA X10i with only 95 system apps and the phone is running brilliantly with 80MB memory free at idle.
If you respect the fact the XPERIA X10i is not an XPERIA Z1, I think it's still an amazing phone even this many years on.
