Well its already been released in some parts of Europe thier is a rumour that it might be released on Monday when the Note 2 comes out. Have been considering getting my one rooted then flashing the official jelly bean rom but think I will wait just in case I brick the phone
I've just 'moved' from iPhone to Android with the Galaxy S3 and I'm still getting used to the different UI. Having seen the Nexus 7 running Jelly Bean I can't wait to get it on the S3!
I've updated already - got it done on Thursday. Works well although it's not a drastic difference to ICS. Scrolls through screens much more smoothly and there are a few new tricks included.
