Hmm, other sites reporting about it seemed to indicate that as of today the Prime would be marketed and sold as an ICS device, as new ones would ship with it... didn't see where they stated that the update was being pushed out to existing Primes tonight.
Will be awesome to see that come through in the next couple of hours though...
This is kind of odd - is anyone else's "Check Update" button grayed out? Just noticed it today (installed .33 over the weekend) Normally if you hit the button and don't have an update available, it'll tell you that right? When I tap mine, there's no accompanying change in the button and no message telling me there's nothing to install.
Yep, appears to be downloading now... it looks like for the past 15 minutes or so the update servers were offline and then they popped up with the update just a few minutes ago
