My Nexus is now sporting CM10.1 stable. It's a shame that I had to use a custom rom just to achieve something so basic, you'd really think the facility to swop, sorry swap
the keys would be there in vanilla Android, but I guess not.
There again, vanilla also forgot to add in a battery percentage icon so it's missing some pretty obvious features, I mean, even IOS had had a battery percentage since around version 3!
Oh well, happy with CM so all good with the world once more.
Thanks for the help.
