Well, it looks like 3 in the UK have finally got round to updating Hero owners with some 2.1 (Eclair) goodness.
My colleague showed me an update that has come OTA, a 78mb file no less and I think this may be it. We cant confirm this as yet until we try and install it this evening.
Please let us know in the comments if you are getting the same update, and how it goes for you.
(Hello to Jenny, a new follower of the site, who thrust her Hero at me asking if this update was important. Yes Jenny, it is :) )
