I got an N70 from my brother which had 3 branded firmware. As others have mentioned if you have branded firmware and try and update using the online Nokia updater then you just get the latest branded firmware (in my case the same version).
So I did a quick bit of surfing and I found someone local who quite happily upgraded my N70 to the latest Nokia firmware for £15 whilst I waited. The result being not having nasty branding, being able to use all the options and having a slightly quicker handset. Sorted!

Get 3rd party to flash the firmware
