Which CM9 ROM for sony ericsson x10i? I was about to download a CM ROM file for my phone, here

Now when I use that (first) uploaded link, it showed me a folder, in which there are a bunch of different versions, such as 


anzu
aoba
mango
etc


and many more.

How do I determine which would be the correct version for me?

My Phone is a Sony Ericsson Xperia x10i, if that is of interest.

I hope this was not asked before, I was searching around for a while. 

Thanks for any help!
I do not think there's any support for the x10 from CM for the v9 release.
For reference:

Xperia Arc =&gt; anzu
Xperia Neo =&gt; hallon
Xperia Pro =&gt; iyokan
Xperia Mini Pro =&gt; mango
Xperia Ray =&gt; urushi
Xperia Mini =&gt; smultron
Xperia Arc S =&gt; ayame
Xperia Neo V =&gt; haida
Xperia Active =&gt; satsuma
Live with Walkman =&gt; coconut
Xperia Neo L =&gt; phoenix

Edit:
CyanogenMod is a ROM that targets a lot of handsets. A souped up/bloated version of the Stock Vanilla AOSP Android (the ones found on the Nexus series handsets)
The FreeXperia project was founded by jerpelea who (unofficially works for Sony, gets freebies and contributes to porting CM for that handset etc). Also, FreeXperia project is officially merged into the CyanogenMod tree. Not all legacy devices are supported using the CM ROM, especially for the newer v9 and v10 (ICS and JB respectively.
If visiting this Get CM you will actually find that CM is not supporting the legacy devices!
Have not tried FreeXperia, but have heard it is not 100% stable, as some things are broken on it (If anyone wants to correct me, feel free to say so in the comments) :)
