I think I saw this update as early as last week sometime. I had a yellow exclamation mark in my status window, but I was in the middle of shutting down to swap SIMs, and fat fingered the update screen closed.

I had seen the blue square next to "Maemo 5" listed with all the other "available apps" to install, but I thought it was something dealing w/a sysem restore, or something "above my pay grade of understanding".

I had been manually hitting update, since the OP started the thread (I have the 5th post or so) but never saw an alert (in USA). I checked what was "available now" and there it was.
