Anyhow, I updated Just2Clean with a XIP of 5.2.19716. The SYS is still 19188.8.131.52 because I hasn't been able to find a 19716 SYS to port over. The point, though, is that I may finally be able to setup a proper EasyPortOven.
I may release the Just2Clean update, also...
So far, it's stable and I haven't found any bugs. I don't use ActiveSync on PC's, so I don't know if that works, but it works fine for syncing with an Exchange server.
EDGE working fine.
