Last week we saw the first CyanogenMod 9 alpha ROM released from xda-developer member spaarc. Now the FreeXperia developer team has released its own version of CM9.0 (FXP053). Similar to the other version, this ROM is “very unstable” as you would expect. The key things not working in this ROM are camera, wireless hotspot and USB MTP. You can find the download and installation instructions here.
