Yes, my ROM is older (17 may 2004). I was trying to figure out what they improved in the new ROM they sent you. Apparently not much beside locking it and audio parameters.

You're right on those files, I checked xda-developers wiki.

I flashed mine with the new rom, and it shows the right ROM date after I hard reset. However, when I restore my data with activesync, the ROM date goes back to 17May2004. It seems that activesync restore copies over also the old ROM files?! Go figure...I'll have to find a way to stop it from doing that.

I haven't had time to try much else and will probably not have any until the week-end.

I did not try all tests in the diagnostics. I got freaked out by the speaker test

Any luck finding a WM2003SE rom?
