I spoke with vodafone about the firmware and the technical team have said that they should have the update in the next couple of days. Im not sure to about this as i have read that Vodafone have been shocking in the past.

Either way i explained that i can flash the device and load up Nokia offical release and they did not have any problems with this and it will not void your warranty. i plan on trying this tonight for the first time as have heard its not too difficult
