Just a quick follow-up.

I have upgraded my N810 (Singtel) version to diablo using the linux version of the flasher. No problems encountered during the upgrade.

Of course, it is now a stock Diablo-based N810 with no Singtel 'enhancements'. But that does not bother me as I'm not a Singtel subscriber: I got my N810 'cheap' from somebody who was a subscriber.
