I've Launchpad running now on this AU-3.1 and had 1.4.4 running on US-3.1 w/ 3G-Euro-Mod before without any issues (except the well known & non-kernel-related like 3G-icon etc.). So make a Nandroid-backup and just try it. I wouldn't expect any problems with that.

It seems I spoke too early about the 3G-connectivity and battery of the AU-version - today I got it out of the bag with 98% battery after 4.5hrs (which is ok, system seems to have settled during the last night), but the 3G didn't connect. This time I was able to get the connection back by toggling the flight-mode twice.
No more reboot or settings-changes necessary.
