Our fellow Reader posted the following. He seems to have issues with this particular rom so please keep that in mind. Also the Froyo roms are not complete and are still in beta. Hopefully they should get finalized soon. Also thanks to the reader!
hey man, I had problems with Free x10 ROM. On the other hand FROYO 2.2.1 X10 AOSP ROM by TripNRaVeRs MODs (below link to the thread) is working rather well for me. Specifically, I've been using version 024.1 for 2 full days and except not working camera and sometimes shaky (but working) videos it's been great.
