So far multiple official beta ROMs have leaked, the latest being build JE1, which features the updated OS, and is apparently pretty speedy, and has the full complement of Samsung software.
Windows Mobile 6.5.3 brings improved gesture support to the OS which should make the use of touch-screen only devices such as the Omnia 2 significantly easer.
The ROM (in Italian) can be downloaded from the HDBlog forums here.
