Hmmm... are you rooted? Maybe that makes the difference?
Anyway, the newest build is there, I've already installed and it works good (I see no difference yet).
Can we get a changelog please?
And also, I've niticed there's a new firmware 12.5.3.0, it's EU stable, but I'm not sure if I should upgrade... The lateat rom installs ok on 12.5.1.0 global.
