Another rom popped up for xperia mini. The difference this and Owain is that this is build from cyanogen final sources like slade87’s. But right now it’s on an alpha stage and therefore major functions like camera and camcorder is not working. The list of works and don’t :
ADB [ Some small issuses not detecting cable right away – needs to be pull out ] plug in few times]
App2SD [Ext3 / Ext4]
FM Radio [ How wonder ] [Working on it]
Camera / Camrecorder [ How wonder ] [Working on it]
Port 4-corners, SE Input Method, Ant Radio
