For a long time (until I logged a bug report to have to fixed) Nokia didn't provide the UK firmware on the tablets-dev site.. so for some time any UK user who re-flashed would now have the "wrong" firmware.. I hope this doesn't mean they all have invalidated their warranty!!

NSU might be able to do this with Symbian and S40 handsets, but I wonder if it does this with Maemo! Interesting

Besides, installing a different firmware (perhaps not even Maemo) using flasher doesn't require a product code change as debranding would nor does it require 3rd party or nokia internal software to do it..

I think there is a case for "you didn't make it difficult or say it was unauthorized" flasher-3.5 and all the firmware versions are available to all N900 users.. this is why I'd really like some Nokia official input! If it is bad, I'd refrain from suggesting it ever again!!
