UK Vodafone, update worked no problems. Didn't need to make any changes and nothing to really report other than 1) when I ran app manager to check for updates it said "No Updates" but then showed the update in the list. 2) Got a worrying message just as install started saying "Operation Failed" but the install carried on with no problems. All my repos are still in place. Device does seem quicker, I noticed someone mentioned a change to https, hopefully this will stop the bug I have that prevents me downloading large files of https.
