Hopefully, an advantage of flashing to the generic build is that future updates won't be held up by the lack of Vodafone support. I did it last Thursday and it worked fine. The really time consuming bit is backing up and restoring data. It also did me the favour of allowing me to ditch a bunch of unwanted apps in one fell swoop. Whether the update is really worth the wait is another matter. Personally, Opera Mobile has made a bigger difference to my life than PR 1.2.
