I have been mucking about with my phone for the last couple of weeks trying out the Spain/Russian releases of Jelly Bean (Android 4.1.2).
I have had to do this as Vodafone hadn't yet released their own update post-testing, although those with unlocked (XEU) phones may have got it sooner.
Anyhow, today after going back to a vanilla Vodafone ICS install, my phone has officially been updated with the Vodafone release!
It is available OTA and via KIES - I haven't had time to play with it yet but I really wanted to be (one of) the first to blog about it!
Will update later with actual findings...
