No it doesn't from the repositories, Vodafone has a a version 205 firmware that is the only one that has not been updated to version 1.1.1

There is nothing in the vodafone version that is vodafone specific except the hard coded apn that I can see so I personally cannot see any reason for Vodafone to drag its feet.

This has been mentioned many times on other forums and Vodafone themselves stated somewhere as long the firmware was official Nokia firmware the warranties would not be voided.
